Cytoplasm is the clear, gelatinous material found in cells. The cytoplasm takes up a little more than 50 percent of the volume of animal cells and a smaller volume in plant cells.Which of the following is a function of cytoplasm?

contains proteins that aid in cell movement and cell shape

determines which substances can enter or leave the cell

serves as the site of many cellular processes
helps materials move from place to place within the cell

supports and holds the cellular organelles

Answers

Answer:

Gel-like fluid present within the cell membrane (excluding nucleus) is termed as cytoplasm of the cell.

It serves various functions in the cell such as:

  • It supports and hold all the cell organelles and cell parts.
  • It serves as the site of most of the cellular activities or processes.
  • It provides shape to the cell.
  • It contains the cytoskeleton (actin filaments, intermediate filaments, and microtubules) of the cell which helps in maintaining the cell shape, the movement of materials within the cell, cell division and movement of the cell.

Hence, all options are correct except  "determines which substances can enter or leave the cell".

Plasma membrane of the cell determines which substances can enter or leave the cell.

If my memory serves me well, the function of a cytoplasm is being revealed in the last option from the scale represented above: it supports and holds the cellular organelles. I hope you still need the answer because I bet this one is really helpful.

TRUE OR FALSE:The amount and type of precipitation in temperate rainforests is the same as tropical rainforests.

Answers

Answer:

The given statement is false.

Tropical rainforests are located near the equator and receive precipitation generally in the form of rain. These forests receive a large amount of precipitation throughout the year which can range from 80 inches to 400 inches in a year.  

Temperate rainforests are located on higher altitudes as compared to the tropical rainforests. They receive precipitation in the form of rain and snow. They receive less amount of rain as compared to tropical rainforests. They receive precipitation which lies between 40 inches and 60 inches in a year.

Thus the amount and type of precipitation in tropical and temperate rainforests are different.


definitely false. a tropical rainforest would have much more precipitation.
