How many times can an electron microscope (EM) magnify an object?
40,000x
True or False? Ribosomes in plant cells use the energy in sunlight to make food.
False...chloroplasts
Fill in the blank. The BLANK reticulum is a system within a cell that creates passages through which materials can pass.
endoplasmic
You are a scientist observing cells that contain chloroplasts. What type of cells would you conclude they are? Plant or animal?
plant because only plant cells contain chloroplasts
Which organelle would you NOT find in an animal cell? lysosome, chloroplast, vacuole
chloroplast
True or false? Plant cells often have one large, central vacuole.
True...animal cells have small vacuoles
True or False? The cell theory states that all animals are made of one or more cells.
False...all living things.
This is the thin, flexible covering that surrounds all types of cells.
cell membrane
You are a scientist observing cells with several, small vacuoles. What type of cells would you conclude they are? Plant or animal?
animal cells because plant cells have one large, central vacuole
Why can you NOT see cells with the unaided eye?
They are too small.
What is the best tool for studying cells?
microscope
True or False? Plant cells and animal cells have all the same organelles.
False...have some of the same organelles
What is the basic unit that makes up all living things?
the cell
The cell is the smallest/largest unit of a living organism.
smallest
This is the rigid outer layer in plant cells only that surrounds the cell membrane.
cell wall
Fill in the blank. The golgi BLANK receives proteins, then processes them for "shipment" outside the cell.
apparatus
This is the thick liquid between the cell membrane and the nucleus.
cytoplasm
You are a scientist observing cells that ALL have lysosomes. What type of cells are they most likely?
animals cells because lysosomes are rare in plant cells
Anton van Leeuwenhoek observed the first living cells with a microscope. Where were these cells?
in a drop of water
What is the general name given to all the smaller structures in a cell that perform specific functions?
organelles
Cells come from other organelles/cells.
cells
What is the name of the pigment that gives plants their green color?
chlorophyll
This organelle directs the activities of the cell and stores the DNA.
nucleus
You are a scientist observing cells that ALL contain lysosomes, and each has a cell wall. What type of cells would you conclude they are? Plant or animal?
plant because animal cells don't have a cell wall
Which organelle is known as the "power plant" of the cell?
mitochondria
