Animal Cells
This organelle functions as the powerhouse of the cell and helps to produce the energy the cell needs to perform its functions.
Mitochondria
This large organelle is the storage center for water, food, and wastes in plant cells.
Central Vacuole
This organelle captures energy from sunlight and uses it to produce food for the cell through photosynthesis.
Chloroplasts
How many main ideas are in the cell theory?
3
A cell is the basic unit of ___________ and _______________ in all living things.
structure, function
This organelle helps break down food and old cell parts to be used again.
Lysosomes
What are the small purple dots that are attached to the endoplasmic reticulum?
Ribosomes
This organelle acts as the clear gel-like fluid that helps give the cell its shape, hold the organelles in place, and distribute nutrients throughout the cell.
Cytoplasm
How did Rudolf Virchow contribute to cell theory?
Discovered cells are only made from other cells
These are tiny structures within the cell that carry out specific functions.
organelles
What is the large maze like organelle connected to the nucleus?
Endoplasmic Reticulum
True or false: plant cells contain lysosomes
false
This organelle receives, packages, and distributes materials from the ER and sends it off to other parts of the cell. It is known as the warehouse of the cell.
Golgi Apparatus
What are the three main ideas of the cell theory?
1. All living things are made of cells
2. Cells are the basic unit of structure & function of living things
3. All cells come from pre-existing cells
This organelle functions as the protein producing factories of the cell. Some of these organelles are attached to the endoplasmic reticulum, while others are free-floating within the cytoplasm.
Ribosomes
What is the substance that fills the cell?
Cytoplasm
What type of cells are plant cells?
Eukaryotic cells
This organelle acts as the brains of the cell and directs all of the cells activities. It also stores thin strands of genetic material called chromatin.
Nucleus
How did Robert Hooke & Theodore Schwann contribute to cell theory?
Hooke: gave the names "cells"
Schwann: discovered all animals are made of cells
This organelle functions as the "window screen of the cell." It is semi-permeable and allows certain materials in the cell, and keeps other materials out. It is also the outermost layer of the animal cell.
Cell Membrane
What are the two types of Endoplasmic Reticulum and what makes them different?
Smooth & Rough ER. Rough ER holds ribosomes, smooth does not.
What organelles do only plant cells contain?
Cell wall, central vacuole, chloroplasts
This organelle transports proteins and other materials received from the nucleus, and sends them to the Golgi apparatus. It is known as the highway of the cell.
Endoplasmic Reticulum
How did Anton Van Leeuwenhoek & Matthias Schleiden contribute to cell theory?
Leeuwenhoek: First person to observe living cells through a microscope
Schleiden: Concluded that all plants are made of cells
True or False: Eukaryotic cells contain a nucleus while prokaryotic cells do not.
True
