POST BIO TEST STUDY METHOD

Substances enter any plant or animal by passing through — This structure gives both plant and animals cells their shape.

Cell membranes, which control the movement of materials in and out of cells.

Many animals have internal or external skeletons that provide support and structure. Which of the following parts of plant cells play a similar role?

Cell walls

Which part of the cell is responsible for controlling the activities of the other parts of the cell? It is like the brain.

nucleus

Jelly like organelle and holds all of them in place

Cytoplasm

Creates energy for the rest of the cell, power plant of the cell.

Mitochondria

After proteins are made, they must be sorted and packaged in preparation for use by the cell. Where does this take place?

Golgi Body

What part of the cell holds all the excess food and water in a cell? It is much larger in plant cells than animal cells.

Vacuole

This is the part of the cell where proteins are produced.

Ribosomes

This part of the plant cell absorbs light and gives the plant its green color. It is where photosynthesis happens and is like a chef.

Chloroplasts

This part of the cell is similar to a highway. Things are able to be transported around the cell through this organelle.

Endoplasmic Reticulum

Smooth ER

Series of double membranes that loop back and forth between the cell membrane and the nucleus, filling the cytoplasm.

Rough ER

Series of double membranes associated with ribosomes, involved in protein synthesis.

Lysosomes

Organelles that contain digestive enzymes, responsible for breaking down waste materials and cellular debris. Produced by Golgi Body

What is the Light Microscope used for? (we used in class)

Display living things

What is the Scanning microscope used for?

Surface details of living things

what is the Transmission microscope used for

inside of living things

endosymbiotic theory

theory that explains how eukaryotic cells came

first type of cell

bacteria

How did eukaryotic cells come?

Large Prok cells engulfed small prok cells and the small cells produced energy and lived together inside the bigger cell.

Why are cells small?

So they can get all their nutrients from the cell membrane

How many cells is bacteria?

1

Cell Theory

States all living things are composed of cells 

Cells are the basic structure/function unit of life

All cells come from pre-existing cells.

What did Robert Hooke do?

observed cork from crude microscope
named cells

Matthias Schleiden

all plants are made of cells

Theodor Schwann

all animals are made of cells

Rudolf Virchow

Cells come from existing cells
