Biology set 4

Question 1

What is fruit the result of?

Answer 1

Fruit is the result of the maturation of a flower

Question 2

Fruit is only found in what type of plant?

Answer 2

An angiosperm as they are the only ones that have flowers

Question 3

What is the scientific way to describe a fruit?

Answer 3

A fruit is the ripened ovary of a seed-bearing plant which contains its seeds

Question 4

What happens as a seed develops?

Answer 4

As the seed develops, its ovary begins to ripen and the ovary wall (the pericarp) becomes fleshy (like berries or apples) or forms a hard coating (beans, wheat, tomatoes)

Question 5

Why is a tomato a fruit and not a vegetable?

Answer 5

Because it grows from a flower!!

Question 6

What makes plants different from other organisms?

Answer 6

Plants are self feeding.

Question 7

What is an autotroph?

Answer 7

An autotroph is a self feeding organism

Question 8

How do plants make their own food?

Answer 8

Plants make food through photosynthesis

Question 9

What are humans called?

Answer 9

Humans are heterotrophs, which means gets food from the outside

Question 10

What is photosynthesis?

Answer 10

Photosynthesis if the process in which light energy is converted to chemical energy.

Question 11

What does chlorophyll do?

Answer 11

Chlorophyll pigments in the chloroplasts use water and carbon dioxide from the air which both store energy in their chemical bonds.

Question 12

What are carbohydrates?

Answer 12

Carbohydrates are types of sugars (sucrose is table sugar)

Question 13

What are two carbohydrates in plants?

Answer 13

Plants have starch and cellulose, and pectin in the fruit

Question 14

Where are carbohydrates stored in plants?

Answer 14

Plants store carbohydrates in their leaves and stems, or fruit or roots (carrots)

Question 15

What is respiration?

Answer 15

Respiration is the opposite of photosynthesis.

Question 16

Describe the process of respiration.

Answer 16

Oxygen reacts with sugar in the plant cell releasing chemical energy, the energy is given to ATP Adenosine triphosphate and transported to the cell to be used up.

Question 17

What does respiration release off as ‘garbage’?

Answer 17

The end result of respiration is carbon dioxide and water.

Question 18

What time of day can respiration happen?

Answer 18

Day or night

Question 19

What time of day can photosynthesis happen?

Answer 19

Photosynthesis happens only during sunlight hours

Question 20

What is transpiration?

Answer 20

Transpiration is another word for evaporation of the water from the surface of leaves and stems

Question 21

Where does water that comes from respiration exit a plant?

Answer 21

Water exits a plant through stomata

Question 22

What are stomata?

Answer 22

Stomata are tiny pores in the leaves that can open and close

Question 23

How does carbon dioxide get into a plant?

Answer 23

Carbon dioxide gets into a plant through the stomata

Question 24

How does water first get into a plant?

Answer 24

Water gets into a plant through the roots

Question 25

What is osmosis?

Answer 25

Osmosis is the name of the process where water moves up a plant’s roots.

Question 26

What is xylem?

Answer 26

xylem is the specialized tissue that water travels along inside a plant.

Question 27

How does a plant conserve water during dry times?

Answer 27

The plant can close the stomata to decrease evaporation

Question 28

What is the problem with closing stomata?

Answer 28

When the stomata close carbon dioxide can’t get in, so the plant has no energy source

Question 29

What is the result of less photosynthesis?

Answer 29

The plant will slow down growth if it doesn’t get enough energy.

Question 30

How have plants adapted to not being able to move around to find nutrients?

Answer 30

The plant balances its water intake, evaporation, and photosynthesis so it can survive in a variety of habitats.

Question 31

What is a biofuel?

Answer 31

A biofuel is a fuel made from organic material such as plants or algae

Question 32

What are ethanol and biodiesel?

Answer 32

Ethanol and biodiesel are types of biofuel that are already in use to reduce our dependence on fossil fuels.

Question 33

What is ethanol?

Answer 33

Ethanol is a type of alcohol made from corn and wheat. Most of our gas already has 5-10% ethanol in it. It is made in Canada and uses the parts of wheat and corn that are usually thrown away.

Question 34

What is biodiesel fuel?

Answer 34

Biodiesel is made from chemically reacting fat/oil and alcohol.Most biodiesel comes from canola oil, but can come from algae and soybeans or waste vegetable oil from restaurants.
