Plant Functions
100
This regulates the amount of light passing through the slide specimen on the microscope stage
What is a diaphragm
100

The powerhouse of the cell. (produces ATP)

What is the mitochondrion?

100

The movement of molecules from an area of high concentration to an area of low concentration.

What is Diffusion?

100
This tissue of the plant responsible for transporting water and dissolved minerals is made up of "dead cells"
What is a xylem
100
A tree growing upright on a steep downhill slope is exhibiting this type of tropism
What is negative gravitropism
200
This is the ability to distinguish between two structures that are close together
What is resolution
200
This part of the cell is like a storage closet
What is a vacuole
200

Adding energy has this effect on the process of Diffusion. (eg. heat or agitation/mixing) 

What is increase the rate of diffusion?

200
This environment relative to the cell is formed when root cells take up dissolved minerals from the soil
What is a hypotonic environment
200
This process in the plant creates enough force to draw the water up from the stems to the leaves
What is transpiration
300
One of the drawbacks of this microscope is that it is difficult building a three dimensional picture of the cell from very thin sections
What is Transmission Electron Microscope
300

This organelle is primarily involved in packaging.

What is the Golgi Body?

300

The diffusion of water across a semi-permeable membrane.

What is osmosis?

300
After photosynthesis takes place, the sugar that is accumulated in the ground mesophyll tissue cells are actively transported into these cells
What are sieve tube cells
300
Due to this property water, its molecules are able to stick to the cell walls of the xylem
What is adhesion
400

This scientist was the first to name "cells" after looking at cork.

Who is Robert Hooke?

400

These small organelles are the actual sites of protein synthesis.

What are ribosomes?

400

Movement of substances against a concentration gradient using ATP.

What is active transport?

400
In the leaf, the products of photosynthesis from palisade cells diffuse through this part of the mesophyll tissue
What is spongy mesophyll tissue
400

A plant's growth response toward or away from light.

What is phototropism?

500

The actual length of the object in the diagram given a scale of 1.0cm = 0.10mm if the object appears to be 2.5 cm.

What is 2.5 mm?

500

These organelles contain digestive enzymes to break down waste or invaders.

What are lysosomes?

500

The process of a cell membrane folding inward to ingest a large particle.

What is endocytosis (or phagocytosis)?

500

Specialized cells that control the opening and closing of stomata.

What are guard cells?

500

This specific mechanism explains how water is pushed upward from the roots during the night when transpiration is low.

What is root pressure?
