Answer: Chromosomes
Explanation: Chromosomes contain a cell's DNA. When a cell divides, the chromosomes must replicate. There are two types of cell division. Chromosomes undergo a different process depending on the type of cell division. It is important that chromosomes replicate properly so that each resulting cell has the correct amount of DNA after division.
<h2>Events in Development of Plants</h2>
Explanation:
The events in the development of plants is as follows:
1. Cyanobacteria begin to photosynthesize.
Cyanobacteria which are commonly called as Blue green algae are Prokaryotes.
They are aquatic and photosynthetic, it means, they live in the water, and can manufacture their own food.
2. Cyanobacteria become the chloroplast of plants.
Cyanobacteria have the endosymbiotic plastid. Eukaryotes or plants considered to have evolved from endosymbiotic cyanobacteria.
3. Bryophytes become the first land plants.
Bryophytes are the first land plants to be evolved from aquatic plants, specifically green algae.
4. Plants evolve to have vascular tissue to transport water.
During the evolution of plants from Bryophytes to Pteridophytes, Pteridophytic plants have vascular tissue i.e. xylem and phloem. Xylem helps in transport of water to various parts of the plants.
