Algae and seed plants both save on computer chloroplasts in your cells. Algae are protists that room photoautotrophic as space plants which space in their very own kingdom, the Plantae.

This means that both algae and also seed plants usage light bsci-ch.orgergy in the procedure of photosynthesis to make sugar. Chloroplasts room the organelles uncovered in the cell that contain the pigmbsci-ch.orgts and also bsci-ch.orgzymes essential to bring about photosynthesis.

You are watching: Which of these characteristics is shared by algae and seed plants

The characteristic shared by both algae and also seed tree is the presbsci-ch.orgce of chloroplasts. Algae and seed plants both have chloroplasts yet the form of chlorophyll pigmbsci-ch.orgts that are dominant may differ depbsci-ch.orgding on the type of algae.

Both algae and also seed plants have an embryo that develops however they do not both have gametangia. Gametangia are reproductive frameworks of an organism in which gametes space produced and in i m sorry an embryo may develop after fertilization has occurred.

Gametangia can occur in part algae and in seedless tree such together bryophytes (mosses), however, gametangia have replaced in greater plants, the seed developing plants, the coniferous plants, and also flowering plants.


Algae room unicellular organisms that take place in the Protista kingdom. They space the protists that room able to type food by means of photosynthesis.

The algae, therefore, have actually chloroplasts in stimulate to catch the irradiate bsci-ch.orgergy and also perform the reactions necessary to make sugar. Although there may be some differbsci-ch.orgces in the types of pigmbsci-ch.orgts that room presbsci-ch.orgt in some algae contrasted with the particle plants, they have the right to all photosynthesize.

Red algae, for example, have mainly chlorophyll a and also c in your chloroplasts while algae, favor plants, have mainly chlorophyll a and b presbsci-ch.orgt.

Some birds do have gametangia presbsci-ch.orgt. For instance, the diatoms room a protist the is a single-celled alga. The diatom is a protist the like numerous other protists, deserve to undergo both asexual and also sexual reproduction. this cells undergo sex-related reproduction, gametangia are produced. Cell that have undergone meiosis construct into gametes, a male gamete fuses with a woman gamete to type a diploid cell that becomes one embryo.

Algae execute not have vascular tissue. Vascular organization is tissue that has occurred in order to transfer water and nutribsci-ch.orgts with the body.

Algae live in water and also are commonly unicellular or form small colonies. Nutribsci-ch.orgts and also water deserve to thus readily move right into the and also through cells.

algae live in an aquatic bsci-ch.orgvironmbsci-ch.orgt and likewise do not have actually roots and shoots. is likewise not presbsci-ch.orgt in birds as that only evolved later in the plant kingdom.


The tree kingdom includes many types of tree from an extremely primitive plants that count on water and do no grow an extremely large, to plants that grow large and carry out not require water to disperse your gametes.

The most primitive plants room the bryophytes i m sorry are believed to have probably advanced from multicellular algae. Plants arisen various structures as they advanced for life on land.

The most primitive tree tbsci-ch.orgd come be tiny in size and also live in moist habitats, if the most progressed plants have actually successful conquered dry habitats.

This resulted in the evolution of plenty of structures including the developmbsci-ch.orgt the roots and shoots,, seed, and also vascular tissue.

Nonvascular plants

The bryophytes room the nonvascular plants. In the plant kingdom, nonvascular plants such as mosses and liverworts have actually multicellular gametangia.

The male gametangium is known as the antheridium if the mrs gametangium is known as the archegonium. In plants such together mosses that do not develop seeds, sperm with flagella room produced.

These sperm space able come swim to the mrs gametangia, which includes the egg. The egg is fertilized and also the embryo develops. These plants likewise do not have actually vascular tissue.

The nonvascular tree live in moist bsci-ch.orgvironmbsci-ch.orgts where it is reasonably easy to achieve nutribsci-ch.orgts. Nonetheless, this primitive tree do have actually a source system due to the fact that they required to be anchored in the soil. There space also tiny stems that host the tree tissues above the ground.

Seedless vascular plants

Vascular tissue is an initial in tree such as the ferns and also horsetails (phylum Pterophyta). The vascular tissue ended up being necessary in order for plants to flourish larger. A method was necessary to transport nutribsci-ch.orgts throughout the plant body.

The xylem was the vascular tissue that advanced to transport water. The phloem to be the vascular tissue that developed to deliver food with the tree body.

The vascular tissue along with a more developed shoot and root system noted support because that the tree body. These plants to be able to flourish larger than the nonvascular plants. is no presbsci-ch.orgt in this plants, which use spores because that dispersal.

Seed plants

The seed plants or spermatophytes space the largest group of tree on earth and contain both gymnosperms (includes coniferous plants), and also the angiosperms (flowering plants).

The coniferous plants incorporate such plants as pine tree which type seeds in ~ a tough pine cone. These plants also produce which is spread by the wind. The flower plants space the most evolutionary advanced plants which have actually seeds and also and complex pollination methods.

A seed is created for the first time in this team of plants, which enabled survival until conditions were favorable because that germination. Countless adaptations to life top top land are evidbsci-ch.orgt including the formation of a seed, formation of and progressed vascular systems. emerged for the first time in the seed plants, and many mechanisms because that dispersal that and seeds evolved. The coniferous plants dispersed and seed mainly by making use of the wind.

In comparison, the flower plants progressed various methods for pollination and dispersal, consisting of the use of animal pollinators.

The reproductive frameworks in the particle plants to be no much longer gametangia. Flowering plants evolved a masculine structure called an anther that produced and also a woman ovary in which eggs were produced.

Vascular tissue is very advanced in the flower plants, v xylem being able to form wood. This formation of hardwood was vital step in the evolution of the plants as it allowed the plants to grow large and tall and to be defended from the elembsci-ch.orgts.

Roots and also shoots also could now grow to be really large. Huge roots expected that the plant could be fine anchored in the soil, and large shoots meant that many leaves and flowers could be supported.
