The organelles that are different from plant & animal cells
What are:
lysosomes, cell wall, chloroplast
The type of transport that requires energy
What is active transport?
The plant is divided into these systems
What is shoot system & root system?
the chemical equation for photosynthesis
What is:
CO2(g) + H2O(g) -light/chlorophyll-> C6H12O6(aq) + O2(g)
Compare a simple and compound light microscope
What is simple light microscope has one handheld lens, compound microscope has 2 lenses
Is semi-permeable and made up of a phospholipid bilayer
What is the cell membrane?
The cell expands during osmosis due to this reason
What is hypotonic solution? Concentration of solutes is higher inside of the cell - water moves in
The stomata is located within this region
What is a lower epidermis layer?
What is:
1) root pressure
2) cohesion
3) adhesion
4) transpiration pull
Who is Anton van Leeuwenhoek
List the order from most complex to least complex:
atoms, cells, organs, organelles, tissues
What is:
organs, tissues, cells, organelles, atoms
The types of active transport
what is:
1) active transport
2) endocytosis - phagocytosis & pinocytosis
3) exocytosis
Area that allows for movement of gas and nutrients around the leaf
What is spongy mesophyll layer?
Describe what happens to the plant and plant cells in a hypertonic environment
What is the plant will wilt and the plant cells become plasmolyzed (membrane pulls away from the wall - shrinking)
Newer microscopes are improved in these 3 areas
What is:
1) magnification
2) resolution
3)contrast
These scientists came up with what experiments to dispute spontaneous generation
Who are:
Francesco Redi - meat in jars experiment
Louis Pasteur - broth in flasks experiment
What is facilitated diffusion?
What is carrier & channel proteins
These cells are living but do not contain a nucleus within the leaf structure
What are the sieve tube cells?
Once CO2 is in the leaf, what is the path it travels before being used in photosynthesis
What is:
stomata > spongy mesophyll > palisade layer > chloroplast (cytoplasmic streaming) > light > photosynthesis
This happens to the field of view as we increase magnification of objective lens
The three parts of cell theory
What is:
1) all living things are made up of 1 or more cells
2) cells are the smallest unit of life
3) all cells are produced from pre-existing cells through cell division
Cell 1 SA/V ratio = 5:1
Cell 2 SA/V ratio = 6:2
Is cell 1 or 2 more efficient?
What is cell 1?
(Larger Sa/V ratio)
This layer is also known as the ground tissue
What is the mesophyll layer?
The ways in which glucose is used
What is:
glucose is stored until needed, converted into ATP energy then used for cellular functions & growth
The 4 microscope formulas
What is:
1) dFOV2 = (dFOV1 x mag1)/mag2
2) drawing mag(scale) = drawing size/actual size
3) actual size = dFOV/times across
4) total mag = mag ocular lens x mag obj lens
