Question 1

Angiosperms can be dioecious or monoecious and they go through sexual production (Raghavan, 1999). Angiosperm flowers are considered to be hermaphroditic or androgynous because the same flower contains both female and male gametophytes. However, angiosperm flowers with only female gametophytes are incomplete and considered to be either a carpellate flower containing only female parts or a staminate flower containing only male structures. The male reproductive structure of the angiosperms is known as andoecium. The anthers that are found in the stamens of the angiosperms contain pollen sacks, which have the microsporocytes. The cells go through a process known as ...

Compare and contrast the structure and function of the three simple tissue types: parenchyma, collenchyma, and sclerenchyma.

Parenchyma cells refer to plant cells in the leaf that are usually alive at maturity. They have cell walls that are thin and flexible. They generally have a central vacuole that is large. They have a polyhedral arrangement. They are involved in carrying out photosynthesis, storage functions, and other metabolic functions. Most of these cells have the potential to undergo differentiation generating other cell types in certain conditions. For instance, when the plant is injured and there is a need for repairing and replacing organs. Their large central vacuoles enable them to store water, regulate intake of ions and ...
