Chapter 4 Study Guide

Relate a cell to a factory!

Compare and Contrast a prokaryotic cell with a eukaryotic cell.

Compare and contrast an animal cell with a plant cell.

List two things a chloroplast produces that are essential for life.

What is the double membrane that surrounds the nucleus?

Main office = nucleus Packaging center = golgi body Factory doors = cell membrane Electricity generator = mitochondria

Compare = prokaryotic and eukaryotic cells both contain DNA

Contrast = “pro”karyotic cells have no nucleus and a “euk”aryotic cells has a nucleus

Compare = Plant and animal cells are both eukaryotic.

Contrast = plant cells have a cell wall and chloroplast, animal cells do not

Why is surface area an important factor in determining cell size?

What is the name of the organelle that regulates what enters and leaves the cell?

Endoplasmic reticulum

Cells, tissues, organs, organ systems

chloroplasts

Golgi body (apparatus or complex)

The cell may become too large to take in enough food and get rid of enough waste.

Plasma membrane

The size to which a cell can grow is limited by its

Are cell walls found in animal cells?

chlorplasts

Where is ATP produced?

In the mitochondria
