Life Science Quiz 2

Question 1

What are the similarities between photosynthesis and cellular respiration

Answer 1

They are opposite processes. Photosynthesis is in plant cells and some bacteria where sunlight carbon dioxide and water are used to make glucose. The glucose process is also made in cellular respiration in plant and animal cells its broken down with oxygen to make carbon dioxide and water

Question 2

Formulas for photosynthesis

Answer 2

Carbon dioxide + water + light energy-> glucose + water
6CO2 + 6H2O + light -> C6H12O6 + 602

Question 3

Formulas for cellular respiration

Answer 3

Glucose + oxygen -> carbon dioxide + water + energy
C6H12O6 + 602 -> 6CO2 + 6H2O + energy

Question 4

Passive transport

Answer 4

The movement of substances across a cell membrane without the use of energy. It relies on concentration gradients moving substances from an area of high to low concentration.

Question 5

Active transport

Answer 5

Requires energy to move substances against the concentrated gradient. From area of low to high concentration

Question 6

Osmosis

Answer 6

A specific type of diffusion which involves water molecules. It’s the movement of water form an area of low to high concentration.

Question 7

Diffusion

Answer 7

The movement of the solute form a area of high to low concentration

Question 8

Cell differeation

Answer 8

The process of which a less specialized cell becomes a more specialized cell it’s important for multicellular organisms because it allows the cells to develop specific functions that work together to the working of a organism
