Answer: cotyledon, seed leaf within the embryo of a seed.
Answer:
Active Transport
Explanation:
Active transport is the process of transport of substances from region of their lower to that of higher concentration. Since the transport occurs against the concentration gradient, it is energy requiring process and needs input of energy to occur.
In given example, liver cells transports vitamins against the concentration gradient in energy dependent manner. Therefore, it is an example of "active transport".
Answer:
Xylem developed to transport water from the plant’s roots to the rest of the plant.
Explanation:
A waxy cuticle is usually present to reduce water loss, whereas spines are often in place that help plants avoid being eaten by herbivores.
Stomata are key for gas exchange, and actually permit the release of water. Water is taken up through the roots, not the stomata
All plant cells have nuclei, which is the organelle in which DNA is stored. The seeds did not develop to provide a place for the storage of genetic information.
However, the xylem is an important part of the plant vascular transport system that ensures water is transporter from the roots to the leaves. This is an important adaptation for land plants as it ensures all parts of the plant get a water supply, particularly the leaves that are undergoing photosynthesis.
