CELL WALL- provides support and protection
CHLOROPLAST- includes the chlorophyll which give leaves a green color.
Answer: <span>
The cell has the shape of a rectangle.
What appears to be a large space can be seen inside the cell
</span><span>Increasing the light source reveals green dots inside the cell.
The only cell that has a rectangular shape is a plant cell duo to the cell wall.
The large spaces inside the cell are the vacuoles.
The green dots are chloroplasts.

<span>mtDNA analysis is the best DNA technology to use. In DNA fingerprinting scientists run a gel electrophoresis of the subject's DNA in order to establish the banding patterns of the DNA fragments. People will always share half of their DNA with a parent. SO half of an individual's banding pattern will match half of their parent's DNA banding pattern. If someone is missing is found then scientists can compare the DNA fingerprint or banding patterns to see what the likelihood is of them being related.</span>
Answer:
Number <u>3</u> is the chloroplast. The chloroplast helps the plant obtain food by <u>photosynthesis</u>. Number <u>1</u> is the central vacuole. The central vacuole helps a plant maintain its structure by <u>turgor pressure</u>.
