Cell Theory
Write the LAST NAME of ONE of the scientists mentioned in the notes that contributed to the Cell Theory.
Hooke, Leeuwenhoek, Schleiden, Schwann, Virchow
Plants are made of what type of cells, prokaryotic or eukaryotic?
Eukaryotic cells
This organelle controls the cell’s activities and holds its DNA.
Nucleus
This organelle is a rigid structure that gives plant cells support and shape.
Cell Wall
Active transport requires energy from what molecule?
ATP
This scientist first observed tiny chambers in cork and called them “cells.”
Hooke
What type of organisms are always UNICELLULAR, prokaryotes or eukaryotes?
Prokaryotes
Name the organelle: Tiny structures that assemble proteins; found floating in cytoplasm or on rough ER.
Ribosomes
This is a large organelle found in plant cells that fills with water and stores other materials.
Large Central Vacuole
What phrase describes a membrane that allows some substances to pass through but blocks others?
Selectively Permeable Membrane
Name ONE of the three statements of the Cell Theory.
All living things are made of cells.
Cells are the basic unit of structure, function, and organization.
New cells come from existing cells.
Name something that you would find in eukaryotic cells, but not prokaryotic cells.
Nucleus; Membrane-Bound Organelles
This organelle converts sunlight into chemical energy.
Chloroplast
These structures help animal cells divide and are found only in animals.
Centrosome/Centrioles
What type of cell transport moves a solute from an area of high concentration to low concentration WITH the help of a transport protein?
Facilitated Diffusion
Name the scientist that concluded news cells only come from existing cells.
Virchow
Name an organelle that you would only find in PLANT cells, but not animal cells.
Chloroplast, Cell Wall, Large Central Vacuole
This organelle is where lipids are made and where drugs/alcohol are broken down.
Smooth ER
This part of the cytoskeleton helps the entire cell maintain its shape and move.
Cytoskeleton
What component of the cell membrane helps cells identify and recognize each other?
Carbohydrate chains
Name the scientist that concluded that all animals are made of cells.
Schwann
Name an organelle that you would only find in ANIMAL cells, but not plant cells.
Centrosome (Centrioles), Lysosome
This organelle breaks down old cell parts and helps defend against bacteria
Lysosomes
There are TWO organelles found in cells that have their own DNA and ribosomes (other than the nucleus). What are they?
Mitochondria and Chloroplasts
What component of the cell membrane controls the fluidity of animal cell membranes?
Cholesterol
