Card preview (24)
Jeopardy! Flexible barrier that surrounds the cell content, allowing the cell to interact with its environment.
The cell membrane
Jeopardy! These organelles break down engulfed pathogens, nutrient molecules, and components of the cell itself that are no longer functional (aka: trash).
What are lysosomes?
Jeopardy This cellular component visible under the microscope protects the interior of the cell from its environment. It also limits the movement of specific materials into and out of the cell.
What is the cellular membrane?
jeopardy These organelles are involved in cellular metabolism, specifically the production of energy via aerobic respiration.
What are mitochondria?
define cytosol
The fluid contained within a cell. In contrast, the cytoplasm includes both the intracellular fluid and all of the extranuclear organelles.
Jeopardy This cell component visible under the microscope includes both the cytosol and the organelles*. *except the nucleus
What is the cytoplasm?
Jeopardy In animal cells, this organelle serves as the location for DNA in its chromatin form.
What is the nucleous?
Jeopardy! Organelle composed of two subunits where protein are synthesized.
What is the ribosome?
Jeopardy This molecule controls all cell activity.
What is DNA: deoxyribonucleic acid
Jeopardy The organelle stores material produced by the cell and transports it to the cell membrane and outside the cell.
What is the Golgi apparatus
Jeopardy THis organelle transports material from one part of the cell to another.
What is the Endoplasmic reticulum
Name this organelle
Endoplasmic Reticulum
Jeopardy These organelles are tge cellular machinery responsible for making proteins
What are Ribosome?
Name this organelle
Ribosome
Identify Contains all organelles and many other dissolved substances.
Cytosol
Identify this organelle This environment is hospitable for most cell activities.
Cytoplasm
Identify 3 roles of… The cell membrane
1)Forms a barrier and protects cell. 2)Let’s stuff in: Lets nutrients and other materials get absorbed. 3)Let’s stuff out: Helps waste leave the cell. There are channels all over the membrane that control the substances “ins and outs”.
Identify this organelle: Digest certain nutrients and decompose and recycle various materials.
Lysosomes Tip: Think of the lysosomes as the “Ecocentre” of the cell.
Identify this organelle: Produces energy through cellular respiration.
Mitochondria
Identify: Molecule that controls all cell activities
DNA
Identify: What parts of a cell can you see under a microscope? There are 3 parts
1)The cell membrane 2)The Nucleus 3)Cytoplasm …honestly tho, it depends on the microscope you use, the way the cell
Fiil in the blanks: ____ (1)is a molecule that is shaped like a ____(2) and is located in the ____(3).
1)DNA 2)double helix 3)nucleus
Fill in the blank: DNA molecules are made up of 2 long chains linked by pairs of tiny molecules called ____
Bases Also: nitrogen bases
Name the 4 nitrogen bases that bridge the 2 DNA strands (aka “the rungs”).
1)Adenine 2)Thymine 3)Cytosine 4)Guanine
