B: during the early stages of meiosis, chromosomes in a homologous pair exchange segments, the process is called Crossing over.
Thallus<span> (plural: </span>thalli<span>), from Latinized Greek θαλλός (thallos), meaning "a green shoot" or "twig," is the undifferentiated vegetative tissue of some organisms in diverse groups such as algae, fungi, some liverworts, lichens, and the Myxogastria.</span>
Plants, but not animals
Plants must create their own food (glucose) through a process called photosynthesis. To be able to preform this, the cell must have chloroplasts which take in sunlight. Due to plants not having chloroplasts they are unable to carry out photosynthesis
Hope this helps :-)
<span>A mutually dependent relationship exists between chloroplast and mitochondria in the plant cell. Photosynthesis, which occur in the chloroplasts,generates the sugar and oxygen gas that are used in mitochondria for cellular respiration. It generates carbon-dioxide which in turn is used as a carbon source for the synthesis of sugars during photosynthesis.</span>
