Ancient plant ____________________ found in lake bottoms provides scientists with evidence about ancient climates.

I believe it's "pollen".

When the pollen grains are washed down into lakes/rivers, scientists can take a sample of the sediment layers and see what plants were growing at that time. They can then make inferences about the climate and how that affected the plants growing there.

Hope this helps!

Can someone help with the labels for this ?

Answer:

Refer to the attached image for correct labeling.

Explanation:

The diagram is of a plant cell and its organelles.
The nucleus houses the genetic material and controls all life processes.
A plant cell contains one large vacuole in the center that stores water and nutrients.
Chloroplast is the site for photosynthesis. It captures light and utilizes it and carbondioxide to produce glucose.
Mitochondria are called the power house of the cell. Through a process called cellular respiration, they break down the glucose produced in photosynthesis into energy compounds such as ATP as well as oxygen and water.
The endoplasmic reticulum is the site for protein sysnthesis. It contains two parts: the rough endoplasmic reticulum (RER) which contains ribosomes that synthesize proteins and the smooth endoplasmic reticulum (SER) which packages the proteins into transport vesicles.
The nucleus contains the nucleolus that is the site for ribosome assembly.
The cell membrane is a semi-permeable membrane that covers the cell and controls cellular transport.
The cell wall is a hard, outer covering that protects the cell and maintains its structure and shape.
