Ans.

Land plants were evolved on the Earth around 850 million years ago. The ancestors of plants are considered as plant-like single cell organisms. These organisms include tiny protists, that were capable of performing photosynthesis as nearly all land plants perform photosynthesis. An example of photosynthetic protist is green alga.

Thus, 'the ancestors of land plants likely evolved from single-cell, photosynthetic protists, such as green algae.'

The ancestors of land plants likely evolved from green algae.

Further Explanation:

Plant grows in a particular region and mainly makes own food. Plants consists pigments that help in synthesis of food. Some plants are seedless and some plants make seed. Seedless plant does not make seeds; they make spores for example ferns, liverworts, horsetails and mosses. Seed plant makes seed and reproduces like flower plant.

Land plants manly evolved on the Earth approximately eight hundred fifty million years ago. Plant-like single cell organisms are referred as main ancestors of plants. These organisms mainly consists tiny protists that are capable of performing photosynthesis as nearly all land plants perform photosynthesis. An example of photosynthetic protista is green algae.

Algae, phytoplankton, bacteria and plants, are photosynthetic in nature. They use sunlight to make sugar, which then converts into energy. They make their food by photosynthesis. Photosynthetic organisms are mainly green because they contain a chlorophyll pigment which helps in absorbing light.

IgorC [24]

Answer:

(this is a phase i would create in regards to this question)

The duplicphase a phase when cells multiple at a constant rate until they have created a pure offspring

Explanation:

Mitosis takes place in four stages: prophase (sometimes divided into early prophase and prometaphase), metaphase, anaphase, and telophase.
