the Rutherford model, light of any energy should be able to make electrons leave the atom and be emitted. The energy of the emitted electrons should be related to the intensity of the light.

mixer [17]

Answer:

(08) and (32)

Explanation:

To make osmosis happen there has to be a difference in the concentration of solutes, between the inside and the outside of the cell. To valance this difference in concentration, water has to flow towards a place that has a higher number of solutes.

The lipids in the cell's wall make this membrane semipermeable. This allows the passage of specific components only, such as water through aquaporins. Lipids and other elements are of importance in the barrier because they maintain the cell separated from the outside, allowing it to be balanced as regards the different substances that can interact with it.

A cell found in the root of the plant would most likely lack what cell structure.
mestny [16]

Answer:

The cells found in the root of the plant normally lacks chloroplasts, as roots do not perform photosynthesis. The main function of chloroplast is photosynthesis.

Explanation:

The plant cell contains nucleus, cell wall, cell membrane, mitochondria, chloroplasts, vacuole, endoplasmic reticulum, ribosomes etc. Chloroplasts contain green pigments which give green color to the plants. The main function of chloroplast is photosynthesis. During photosynthesis, the plants produce glucose and release oxygen by using carbon dioxide from the air, and absorbing water and nutrients from the soil. Using the glucose in the plants and oxygen, mitochondria produce energy.

The root system of the plants absorb water and nutrients from the soil. The absorbed water and nutrients are then transported to various parts of the plant to carry out processes like photosynthesis, maintaining turgor pressure etc. They have different types of cell which perform some specific functions. These cells also contain cell wall, cell membrane and mitochondria. Mitochondria provides energy for the active transport of water and nutrients. But chloroplasts are absent in root cells as they do not perform photosynthesis.
