Active & Passive Transport
Which kinds of molecules can diffuse through the cell membrane?
small molecules like water, oxygen, and carbon dioxide
What is respiration without oxygen called?
fermentation
What makes up organelles?
macromolecules
How many chromosomes do humans usually have?
46 (two pairs of 23)
Identify an example of a prokaryote
bacteria or archea
What is the difference between active and passive transport?
Active transport requires the cell to use energy
Which pigment is necessary for photosynthesis?
chlorophyll
Which organelle makes proteins?
ribosomes
What is cytokinesis
splitting of the cell after mitosis
Why do cells in multicellular organisms have different shapes?
they have different jobs
definition of osmosis
In which organelle does respiration take place?
mitochondria
DOUBLE POINT OPPORTUNITY:
- For the regular amount of points: identify the building blocks of proteins
- For double the amount of points: identify building blocks for all macromolecules
proteins (amino acids)
lipids (fatty acids)
nucleic acids (nucleotides)
carbohydrates (sugars)
Which is the longest stage of the cell cycle?
interphase
What is one difference between prokaryotes and eukaryotes?
diffusion and osmosis
Identify two organisms that do photosynthesis
plants, algae, and cyanobacteria
What are the 4 types of macromolecules?
proteins, lipids, carbohydrates, and nucleic acids
What are the 3 parts of cell theory?
all living things are made of cells
cells are the basic unit of life
cells come from other cells
Identify one way in which a human and a bacteria are similar. Identify one way that they are different.
Both are made of cells. Bacteria is unicellular and prokaryotic.
Two types of active transport
endocytosis and exocytosis
What does this equation represent? water + carbon dioxide + energy --> glucose + oxygen
photosynthesis
Which organelles are present in a plant cell, but not in an animal cell?
chloroplast and cell wall (and larger vacuole)
In which stage of the cell cycle do chromosomes appear?
atom - molecule - macromolecule - organelle - cell - tissue - organ - organ system - organism
