Question 6

Budding

Answer 6

The process where a new organism starts growing as a small projection or “bud” on the body of the parent organism.

Question 7

Cuttings

Answer 7

Refers to pieces of a plant, typically stems or leaves, that are cut from a parent plant and then planted to grow into new plants.

Question 10

Pollination

Answer 10

The transfer of pollen grains from the anthers to the stigmas of flowers

Question 11

Types of Pollination

Answer 11

Self-pollination
Cross-pollination

Question 12

Self-pollination

Answer 12

Occurs when a pollen grain is transferred from an anther to a stigma of the same flower or to a stigma of another flower on the same plant

Question 13

Cross-pollination

Answer 13

Occurs when a pollen grain is transferred from an anther of a flower on one plant to a stigma of a flower on different plant of the same species

Question 14

Function Of Petals

Answer 14

Function of the petal is to attract pollinators, such as bees and butterflies, by providing visual cues like color and scent.

Question 15

Function Of Stigma

Answer 15

Function of the stigma is to capture pollen grains during pollination, allowing them to germinate and grow pollen tubes for fertilization

Question 16

Function Of Sepals

Answer 16

They enclose and protect the flower bud before it opens. It also play a role in attracting pollinators and protecting the reproductive parts of the flower.

Question 17

Function Of Ovule

Answer 17

It contains the egg cell and surrounding protective layers. After fertilization, the ovule develops into a seed.

Question 18

Function Of Anther

Answer 18

To produce and release pollen grains, which contain the male gametes.

Question 19

Menstrual Cycle

Answer 19

This is a cycle of about 28 days which begins when a female reaches puberty

Question 20

Role Of Progesterone

Answer 20
