Bio 9 Ch 7 Cells

This part of the cell is made up of protein.

• Lysosomes

• Nucleus

• Ribosomes

Answer explanation

Ribosomes are made up of proteins and can be found on the Rough ER.

I provide a cell its structure, shape and help provide movement to it. I am also found in all Eukaryote Cells.

• Cell Membrane

• Cytoskeleton

• Mitochondria

Answer explanation

Cyto means CELL.

Skeletons give something moving, shape and structure.

Eukaryotes - plant and animal cells - have cytoskeletons. Some Prokaryotes have cytoskeletons - for example cilia - but not all of them do.

Cell Theory states that cells are the basic unit of function and all cells come from one another.

• True

• False

I am the organelle found in plants, whose job is to capture the sun's energy. What am I?

• Rough ER

• Cell Wall

• Chloroplasts

Answer explanation

Chloroplasts captures the suns' light to turn it into energy.

Chlorophyll is the green color plants give off.

This part of the cell is responsible for controlling the cell, as well as storing DNA.

• Nucleus

• Golgi Apparatus

• Vacuoles

Answer explanation

Eukaryotes have a nucleus that stores the cells' DNA.

Prokaryotes do have DNA, but they do not house it in a nucleus.

Bacteria and fungi are considered which type of cells?

• Eukaryote

• Prokaryotes

• Hypotonic

Answer explanation

Eukaryotes are animal and plants cells.

Prokaryotes are bacteria and fungus.

Hypotonic is a cell with too much solute inside of the cell.

Animal cells are _____ and need to be _____ to maintain homeostasis.

• Eukaryote Cells, Isotonic

• Prokaryote, Hypotonic

• Eukaryote, Hypertonic

Answer explanation

Animals and plants have eukaryote cells.

Animal cells need to have equal parts of solute for maintain homeostasis; isotonic.

Plants need more water in their cells, therefore, their cells need to be hypotonic; more solute inside the cell.

Hypertonic means there is less solute inside the cell. The cell looks like a raisin.

Prokaryote cells are bacteria and fungus cells.

What does the Smooth Endoplasmic Reticulum make?

• Ribosomes

• Lipids

• Energy (ATP)

Answer explanation

Lipids are fats made by the Smooth ER.

Ribosomes are proteins that can be found on the Rough ER; remember Ribosome starts with the word RIB and ribs are a source of protein.

Mitochondria are the key players in the production of ATP (energy) production.

ATP = energy

A - All

T - The

P - Power

_____ is when the movement of materials from high concentration to low concentration.

• Selectively Permeable

• Osmosis

• Diffusion

Answer explanation

Diffusion: movements of materials from higher concentrations to lower concentrations - in and out of the cell.

Osmosis: This is the diffusion of water. This use Aquaporins (a special protein and funnels to pour) allowing H2O to diffuse quickly in and out of the cell.

Selectively Permeable Membrane: Only allows certain molecules to pass in/out of the cell at a given time.

_____ are specialized structures that help keep a cell alive, like a 'mini organ.'

• Cell Membrane

• Organelles

• Lipid Bilayer

Answer explanation

Cell Membrane is the gate keeper of the cell. It decides what can come in and out of a cell.

Lipid Bilayer:

Lipid means fat(s)

Bi means two

Layer means stacking

Lipid Bilayer: provides the barrier that marks the boundaries of a cell.
