What is an organelle?

An organelle is a type of organism that can live independently.

An organelle is a fluid that fills the cell and provides nutrients.

An organelle is a genetic material found in the nucleus of a cell.

An organelle is a specialized structure within a cell that performs a specific function.

What is the purpose of the nucleus?

To facilitate cell division

To generate energy for the cell

is to store and protect genetic information

To produce proteins for the cell

List two places you can find ribosomes in the cell.

Nucleus

Cytoplasm, Endoplasmic Reticulum

Mitochondria

Golgi Apparatus

If your body didn’t have vesicles, what would happen? (or not be able to happen?)

Vesicles are only important for energy production.

Transport of materials would be faster without vesicles.

Cells would function normally without any changes.

Cells would be unable to transport materials efficiently,

One MAIN goal of the cell is to make ______ because they run your body.

carbohydrates

lipids

proteins

nucleic acids

Draw a phospholipid and label its parts with as many specific terms as you can.

What does hydrophilic mean?

Hydrophilic means having an affinity for water.

Hydrophilic means having no interaction with water.

Hydrophilic means being dry and arid.

Hydrophilic means repelling water.

What does hydrophobic mean?

Attracting water or mixing easily with water.

Being soluble in oil or fats.

Hydrophobic means repelling water or not mixing with water.

Having a strong affinity for moisture.

What is the best way to describe a cell membrane?

A solid wall that protects the cell from external damage.

A selectively permeable barrier composed of a phospholipid bilayer.

A rigid structure that prevents all substances from entering the cell.

A fluid layer that allows only water to pass through.

10.

What is the significance of the cell membrane being selectively permeable?

It prevents any substances from entering the cell.

It allows all substances to freely pass in and out of the cell.

it regulates the internal environment of the cell, allowing essential substances to enter while keeping harmful ones out.

It only allows water to enter the cell while blocking all other substances.

11.

Define homeostasis.

Homeostasis is the maintenance of stable internal conditions in an organism.

Homeostasis is the ability to adapt to external environments.

Homeostasis refers to the growth of an organism.

Homeostasis is the process of cell division.

12.

Which organelle is active in sythesis, sorting, and secretion of cell products?

Ribosome

Endoplasmic reticulum

Lysosome

Golgi apparatus

13.

What 2 substances need to be transported out of all kinds of human cells in order for them to survive?

Proteins and lipids

Carbon dioxide and Nitrogenous waste

Oxygen and glucose

Sodium and potassium

14.

What 3 substances nee to be transported into all kinds of human cells in order for them to surevive?

Glucose, oxygen, water

Sodium, potassium, calcium

Carbon dioxide, nitrogen, iron

Cholesterol, vitamins, amino acids

15.

What purpose do proteins serve in the cell membrane?

Proteins are only involved in the synthesis of lipids in the cell membrane.

Proteins act solely as a barrier to protect the cell from external substances.

Proteins serve as receptors, transporters, and facilitators of cell communication in the cell membrane.

Proteins are primarily used for energy storage in the cell membrane.

16.

The purpose of carbohydrates in the cell membrane is to ?

form the structural framework of the membrane

facilitate cell recognition and signaling

provide energy for the cell

transport molecules across the membrane

17.

distal

farther from the point of attachment

superior

above or higher than

inferior

below or lower than

medial

toward the midline of the body
