Unit B: Section 1

Question 1

The function/structure of a stem is?

Answer 1

Water and nutrients are transported between the leaves and the roots.

Question 2

the function/structure of a leaf is?

Answer 2

produce food for the plant by collecting energy from the sun and changing it to chemical energy (food).take in and release oxygen and carbon dioxide. water enters and leaves the cells of the leaves through guard cells

Question 3

the function/structure of a seed is?

Answer 3

Seeds contain an embryo that will form a new plant. They also contain a food supply for the embryo.

Question 4

The function of cone/flower is?

Answer 4

Both cones and flowers have male and female parts for reproduction.

Question 5

Osmosis

Answer 5

Water from the soil enters root cells by a process called osmosis.

Question 6

Diffusion

Answer 6

Diffusion happens when there is a difference in concentration. Particles move from an area of High concentration to Low concentration. Ex - food colouring in water or perfume in a room

Question 7

Capillary action

Answer 7

Another process that helps water move up through a plant is called capillary action.

Question 8

transpiration

Answer 8

Water particles evaporate from the surface of the leaves and more water particles move up within the plant to take their place.

Question 9

photosynthesis

Answer 9

the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.
“during photosynthesis plants absorb CO₂”

Question 10

cellular respriation

Answer 10

a series of chemical reactions that break down glucose to produce ATP

Question 11

seedling stage

Answer 11

Growth is very fast producing new leaves, roots, stems and their own food. Still need nutrients from the soil.

Question 12

adult stage

Answer 12

A plant is an adult when it produces reproductive structures (flower or cone).

Question 13

ovary

Answer 13

a part of the female reproductive organ of the flower or gynoecium. Specifically, it is the part of the pistil which holds the ovule(s) and is located above or below or at the point of connection with the base of the petals and sepals.

Question 14

stigma

Answer 14

male part of the flower were pollen is store

Question 15

nectar

Answer 15

a sugary fluid secreted by plants, especially within flowers to encourage pollination by insects and other animals. It is collected by bees to make into honey.
