Midterm Study Guide(Science

Question 1

How do plants get their energy?

Answer 1

Plants break down Glucose produced in photosynthesis (Producers)

Question 2

How do animals get their energy?

Answer 2

Animals get energy by consuming other organisms (Consumers)

Question 3

What is the equation for photosynthesis?

Answer 3

CO2+H20+Energy=H12+O2

Question 4

What are the reactants for photosynthesis?

Answer 4

Carbon Dioxide, Water, and Sunlight/Energy

Question 5

What are the products for photosythesis?

Answer 5

Glucose and Oxygen

Question 6

What is the difference(s) between photosythesis and cellular respiration?

Answer 6

Photosythesis-done in the chloroplast, produces glucose and oxygen, can only be done by producers.
Cellular Respiration-creates ATP for organisms, can be done by producers and consumers, done in the mitochondria

Question 7

What are living things made of?

Answer 7

Cells

Question 8

What is the function of the Chloroplast?

Answer 8

Traps light energy and changes it for food for the cell using photosythesis

Question 9

What is the function of the Golgi Bodies?

Answer 9

Modifies/packages proteins and creates lysosomes

Question 10

What is the function of the Cell Wall?

Answer 10

provides protection and structure for plant cells

Question 11

What is the function of the Nucleus?

Answer 11

provides the instructions for making proteins and controls the cell.

Question 12

What is the function of the Vacuole?

Answer 12

A storage bubble within the cell to hold excess food, water, or waste.

Question 13

What is the function of the Endoplasmic Reticulum(E.R.)?

Answer 13

A collection of tubes that can transport proteins and fats throughout the cell

Question 14

What is the function of the Lysosomes?

Answer 14

these breakdown excess, unwanted, or worn-out cell parts

Question 15

What is the function of the Ribosomes?

Answer 15

responsible for creating protiens and can be attached to the ER

Question 16

What is the function of the Cytoplasm?

Answer 16

the gel-like substance that is responsible for holding the organelles in shape and providing the cell with shape.

Question 17

What is the function of the Cell Membrane?

Answer 17

the outer layer of an animal cell that regulates what goes in and what goes out.

Question 18

What is the function of the mitochondria?

Answer 18

changes the energy that the cell gets from it’s food into a form that the cell can use.

Question 19

What are the major differences between plant cells and animal cells?

Answer 19

Plant Cells- Square and cell wall+chloroplast
Animal Cells- Circle and no cell wall/no chloroplast

Question 20

What is Newton’s first law?

Answer 20

An object in motion stays in motion, an object at rest stays at rest, unless acted by an outside force.

Question 21

What is Newton’s second law?

Answer 21

Force= Mass x Acceleration. The relationship between force, mass, and acceleration is all connected.

Question 22

What is Newton’s third law?

Answer 22

Every action has an equal and opposite reaction.

Question 23

What are the 5 parts of a transverse wave?

Answer 23

Rest point, crest, trough, wavelength, and amplitude

Question 24

What is reflection?

Answer 24

Reflection is when light or sound waves bounce off a surface

Question 25

What is refraction?

Answer 25

Refraction is the “bending” of a wave as it travels through different mediums.
