Answer 1

Answer:1. Option D is the correct answer.

Explanations:- Mosses are those plants that does not have the vascular system. These plants does not have xylem and phloem. They have gametophyte as main plant body.

Answer:- 2. Option D is the correct answer.

Explanations:- Apical meristem is the meristem in which cells divides very rapidly. There are two types of meristem based on the location , shoot apical meristem and root apical meristem.

And.3. Option A is the correct answer.

Explanations:- Ferm have sporophyte as dominant part of life. But in case of mosses , gametophyte is dominant part. In fern , sporangia grows on the leaf of sporophyte.

Ans.4. Option B is the correct answer.

Explanations:- The life cycle in which dominant haploid stage is present is called as haplontic life cycle. In this life cycle, zygote divides to form form haploid spore. It is present in algae and mosses.

Ans.5 Option B is the correct answer.

Explanations:- Vertebrate have closed circulatory system. They don't have the open circulatory systems.

Ans.6. Option A is the correct answer.

Explanations:- Flateworm are triploblastic. They have 3 germ layer and bilaterally symmetric.
