Answer:
Leaf cells contain chloroplasts. Photosynthesis happens in the chloroplasts as they hold vitality from the sun. Chloroplasts contain chlorophyll, which influences leaves to seem green.
The tissues of the leaf in the middle of the epidermal cells, into which gases diffuse from the stomata, are called mesophyll. The mesophyll can be additionally separated into two layers, the palisade layer, and the springy layer, both of which are stuffed with chloroplasts, the production lines of photosynthesis.

Abiotic means fake or not living. Trees, grass, and people are living, also know as biotic. The sun is not living, it’s just a ball of hot gas, which is not living.
Answer:
The correct answer to the question is: the level of liquid in Side A will rise.
Explanation:
- Sucrose is formed of two molecules of glucose but the membrane is impermeable to it.
- The given membrane is said to be permeable to water and glucose.
- Through a semi-permeable membrane, molecules tend to move from a region where its concentration is high to another region where its concentration is low by the process of diffusion until its concentration in the two regions becomes equal. This phenomenon is known as Osmosis.
- Concentration gradient of a molecule can be defined as the difference in the concentration of the molecule in two different regions separated by a semi-permeable membrane.
- Considering glucose, the concentration of glucose is low in side A (1M) and high in side B (2M), so it will tend to move from side B to side A down its concentration gradient.
- Considering sucrose, although its concentration is high in side A (2M) but low in side B (1M), it is unable to move as the membrane is impermeable to it.
- Water tend to move from a region where the concentration of solute is low (or water concentration is high) to a region where the concentration of solute is high (or water concentration is low).
- Due to the movement of glucose from side B to side A, the concentration of total solute concentration becomes high in side A as compared to side B. Therefore, water would move from side B to side A.
- Hence the level of liquid in Side A will rise after sometime.
The correct answer of the given question above would be option C. The false statement about an experimental design is that, the residuals are the different types of treatments. The rest of the statements are considered true about an experiment design.
