Cell
The unit of information that occupies a specific place within a chromosome is the ______
Genes
Explain what a gene is
Part of a chromosome that contains hereditary information
What is the role of genes?
Transmission of hereditary characteristics (blue eyes, brown hair)
What is a chromosome?
A structure that contains the dna of a cell
In which part of a cell is a chromosome found?
The nucleus
Which is smaller, a gene or a chromosome?
A gene
What chromosome is a male made up of?
One X and one Y
What chromosome is a female made up of?
Two X
Each human cell has ______ chromosomes, except for sex cells, which have _____ chromosomes
46
23
What is a cell membrane?
The barrier that surrounds a cells components to separate them from their environment
What is diffusion?
Movement of solute particles from an area of higher concentration to an area of lower concentration
What is osmosis?
Movement of solvent particles form an area of lower concentration to an area of higher concentration
(Osmosis/Diffusion) the cell membrane can increase in size after the movement in solvent particles
Osmosis
(Osmosis/Diffusion) The cell membrane stays the same size after the movement of solute particles
Diffusion
(Osmosis/Diffusion) The cell membrane stays the same size after the movement of solute particles
Diffusion
(Osmosis/Diffusion) The cell membrane can decrease in size after the movement in solvent particles

Diffusion
Osmosis or diffusion
Tree absorbing water from the soil which has little water to the roots which has more
Osmosis
Inside a cell, the concentration of salt is 2%. Outside the cell, the concentration is 0%. What’s happening if osmosis occurs
Salt molecules enter the cell
(T/F) The input of a cell describes a substance or amount of energy that enters the cell
True
What are the inputs and outputs of photosynthesis?
Inputs- C02, water, sunlight
Outputs- glucose, oxygen
What are the inputs and outputs of cellular respiration?
Inputs- glucose, oxygen
Outputs- CO2, water, energy
What chemical reaction allows living organisms to use energy?
Cellular respiration
What chemical reaction allows plants to use energy from the sun?
Photosynthesis
What is photosynthesis?
A process where green plants+algae use sunlight. CO2 and water to create glucose and oxygen
What is cellular respiration?
Process where cells convert glucose and oxygen into co2, h20 and energy
Name two organelles that are unique to plant cells
Chloroplasts and cell wall
What do plants need to perform photosynthesis? Name the substance and the cellular component where it is located.
Substance- Chlorophylls
Location- Chloroplast
Name the organelle that performs cellular respiration
