SB1.a (Cell Structures and Homeostasis)
Cell organelles and cell structures aid the cell in maintaining balance between its internal and external environment. This is known as...
What homeostasis
These 3 elements are present in all organic macromolecules.
What are C (Carbon), H (Hydrogen), and O (Oxygen)?
ALL cells have this external phospholipid bilayer responsible for controlling what enters and exits the cell.
What is the cell membrane (plasma membrane)?
These organisms are capable of performing photosynthesis.
What are autotrophs (producers)?
The process of osmosis moves what substance across the semi permeable membrane?
What is Water?
This organelle breaks down waste materials and damaged cell components.
What is a LYSOSOME?
In addition to Carbon, Hydrogen, and Oxygen, Proteins have this addtional element.
What is Nitrogen?
A membrane lets water and solute A cross but blocks solute B. This structure would allow soloute B to cross.
What is a protein channel?
These 3 inputs are necessary to begin the process of photosynthesis.
What are carbon dioxiode, water, and sunlight?
A cell containing 40% water is placed in pure water. The size of the cell will (increase, decrease, or stay the same)
What is increase?
This organelle makes proteins by connecting amino acids in the correct order.
What is a ribosome?
This macromolecule is necessary for the production of quick energy. They can be found in foods like pasta, grains, fruits, and sweet foods.
What are carbohydrates?
A membrane lets water and solute A cross but blocks solute B. Side 1 has more of solute B, while side 2 has less B. Solute B moves across the membrane only if ATP is present. What side will solute B move to?
What is side 1?
BONUS: Take a few minutes to discuss why and write it on your board. 500 points.
What is decrease?
Osmosis is passive transport meaning water will move in what direction (high to low, low to high, or both)
What is high to low?
An organism contains a cell wall, cell membrane, ribosomes, and free floating DNA. There is no evidence of other internal structures. This cell is more than likely what type of cell?
What is a prokaryotic cell/bacteria?
Which macromolecule stores long-term energy and is a major component of cell membranes?
What is a lipid?
The cell membrane has the ability to create extensions to engulf and pull substances into the cell. This type of active transport is called
This is the location of the Calvin Cycle, also known as the dark reaction or light independent reaction.
What is the Stroma?
Draw a diagram using whatever numbers you want for a cell that is hypotonic. Rememeber Hypo...like a hippo

A plant cell loses its ability to store water in its large central compartment. Which organelle is affected?
What is the central vacuole?
A scientist discovers a biological molecule containing carbon, hydrogen, oxygen, and nitrogen. The molecule is made of amino acid chains that fold into a specific shape. Which macromolecule is present?
What is a protein?
This type of passive transport requires the use of protein channels to move large and/or charged substances across the membrane.
What is faciitated diffusion?
What is oxygen?
A cell placed in a salt water solution shrinks because the concentration of solutes is higher outside than inside. This makes the cell which of the following (hypertonic, hypotonic, or isotonic)
What is hypertonic?
