MITOSIS
Complete the sentences below by circling or filling in the correct words.
Mitosis is cell division of (germ, somatic) cells. The purpose of mitosis is to create new cells for
and
Mitosis produces four (different, identical) cells that are (diploid,
haploid)
Answer:
Cells divide and reproduce in two ways, mitosis and meiosis. Mitosis results in two identical daughter cells, whereas meiosis results in four sex cells. Below we highlight the keys differences and similarities between the two types of cell division.
Explanation:
Involves one cell division?
Results in two daughter cells
Results in diploid? daughter cells? (chromosome? number remains the same as parent cell)
Daughter cells are genetically identical
Occurs in all organisms except viruses
Creates all body cells (somatic?) apart from the germ cells? (eggs and sperm)
Prophase is much shorter
No recombination/crossing over occurs in prophase.
In metaphase individual chromosomes (pairs of chromatids) line up along the equator.
During anaphase the sister chromatids are separated to opposite poles.
The diagram below represents a plant cell in tap water as seen with a compound light microscope.
Which diagram best represents the appearance of the cell after it has been placed in a 15% solution for two
minutes?
SOS

(2)
(3)

Answer:
(3)
Explanation:
I believe 3 would be the answer here because when interacting with a salt solution, plant cells will look like that. Hope this helped!
Diagram 3 of the cell will represents cell's appearance after being kept in 15% salt solution.
This will happen because of exosmosis in which the water will move out of the cell causing to to get shrink called plasmolysisWhat is osmosis?It is the process of movement of solvents through a semi- permeable membrane from region of lower solute concentration to higher solute concentration.
There are three types of osmosis:-
Isotonic:- The solutions bring compared have equal concentration of solutesHypotonic:- The solution with lower concentration of solutesHypertonic:- The solution with higher concentration of solutesTo know more about osmosis here

1. Describe the structures of the chloroplast where photosynthesis takes place.
2. What would happen if the stomata of a plant leaf were glued shut? Would that plant
be able to perform photosynthesis? Why or why not?
3. What are the reactants needed to perform photosynthesis? The products?
4. What happens to the products of photosynthesis?
Answer:
In plants, the process of photosynthesis takes place in the mesophyll of the leaves, inside the chloroplasts. Chloroplasts contain disc-shaped structures called thylakoids, which contain the pigment chlorophyll. Chlorophyll absorbs certain portions of the visible spectrum and captures energy from sunlight.
The plant leaf would not be able to perform photosynthesis. The leaf needs to have its chloroplasts facing the sun, so that they can absorb the sunlight to perform photosynthesis.
During photosynthesis, light energy converts carbon dioxide and water (the reactants) into glucose and oxygen (the products).
During the process of photosynthesis plants break apart the reactants of carbon dioxide and water and recombine them to produce oxygen (O2) and a form of sugar called glucose (C6H12O6). The oxygen will leave the plant through the stomata and enter Earth's atmosphere.Explanation:

Shown below are 4 stages (A,B,C,D) (not in sequence) of a certain kind of cell division.
The diagram below shows a cell undergoing mitosis (cell division). The correct order of the stages is B, C, D and A.
Mitosis is a type of cell division in which a parental cell divides to produce two genetically identical daughter cells.
In this case, an animal cell is undergone mitosis because the cell exhibits centrioles (only found in animal cells) and lacks cell walls (only present in plant cells).
The stages of mitosis include prophase, prometaphase, metaphase, anaphase, and telophase.
