Question

Gymnosperms such as Pine Trees have:

1. Flowers that attract pollinators
2. Only one kind of cone, which are male
3. Both male and female cones

2. Which of these is a Eudicot?

1. Cactus
2. Palm Tree
3. Lily
4. Most Grasses

3. In plants, what is the advantage of sexual reproduction (instead of asexual reproduction)?

1. It can happen out of water
2. It creates more nutrient molecules for the developing embryo
3. It produces genetic diversity
4. It can happen in water

4. The main function of Xylem is:

1. To protect the growing seed
2. To transport sugars from the leaves to the rest of the plant
3. To attract pollinators
4. To transport water and minerals from the roots to the rest of the pant

5. The main function of Phloem is:

1. To transport sugars from the leaves to other parts of the plant
2. To prevent drying out
3. Photosynthesis

Answer 1

1) gymnosperms are vascular plants having seeds, but the seeds are exposed that is they do not have flowers, pine trees have both male and female cones in a plant so the answer is c) Both male and female cones.

2) eudicot are angiosperms which have 2 cotyledons in the seeds so palm tree, Lilly, grasses are all monocots having one cotyledon so the answer is a) cacti.

3) the sexual reproduction involves the fusion of gametes from both parents, gametes are formed by meiosis, the process of meiosis involves the recombination between the non-sister chromatids, this changes the allele combination in a chromosome and due to independent assortment of chromosomes the gametes can have any one copy of the chromosomes, these process increases the genetic diversity of the gametes.

so the answer is c) it produces genetic diversity

4) xylem transports water and nutrients from the soil to the leaves and phloem transports sugars from leaves to all parts of the plant so the answer is d) To transport water and minerals from the roots to the rest of the pant.

( flowers attract pollinators, the growing seed is protected by ovary and the seed coat)
