Chapter 1: Cell

​ ​ _______ have cell membranes, mitochondria, vacuoles, cytoplasm, endoplasmic reticulum, and a nucleus. ​

_____ have ALL of those and a BIGGER ​ vacoule

Which of these are part of cell theory?

• all cells come from other preexisting (living) cells

• cells are the basic (most simple) unit of life

• all living things are made of cells

• humans are multicellular

• organisms grow by increasing the size of their cells

Using this image, what organelle is C?

• Cell Wall
• Mitochondria
• Large Cell Vacuole
• Chloroplast

Which of the following are NOT found in animal cells

• chloroplasts and cytoplasm
• chloroplasts and cell wall
• cell wall and cell membrane
• mitochondria and nucleus

What tool do you use to view the cells?

• metric ruler

• Magnifying glass

• microscope

• Telescope

Who looked at cork and named the cell?

• Robert Hooke

• Van Leeuwenhoek

• Robert Brown

• Francesco Redi Cork

Which organelle is needed for plants to make energy?

• vacuole

• cytoplasm

• mitochondrion

• cell membrane

Why is a cell membrane important to both plant and animal cells?

• It stores food and water.

• It controls the activities of the cell.

• It uses energy from the sun to perform photosynthesis.

• It provides a barrier between the cell and its environment.

Which job is performed by the cell wall of a plant?

• maintaining shape and structure

• controlling functions

• breaking down materials

• passing on genetic material

Shayna placed a prepared slide of tissue from Zea mays, a corn leaf, under a microscope. She placed the slide on the stage and switched from low to high power. She used the adjustment knobs to focus the image. When she looked into the eyepiece, she observed many room-like structures. She made a sketch in her journal of her observations.

Which part of the cell theory does Shayna's sketch provide evidence for?

• All cells are invisible.

• All cells come from plant cells.

• All organisms come from seeds.

• All organisms are made of cells.
