1. How does the basic leaf structure suit its function? A leaf is a plant organ that is very crucial for a plant survival. It has a structure that makes it suitable to perform its functions. A leaf normally has a larger surface area so that they are able to absorb sunlight more easily. Sunlight is required by plants for the food making process. A leaf is normally very thin. This allows the carbon dioxide to travel and diffuse in a short distance. Also, oxygen which is usually a by-product, diffuse out easily. A leaf has a green coloring ...

Abstract

This examination paper acknowledges the spectacular diversity of reproductive adaptations for survival of various categories of land plants. It describes a typical life cycle of a land plant that reproduces via spores. It also identifies the different parts of Plant organs and their functions such as cell organelles, parts of a land plant, and epidermal cells. A microscope is an important tool for examination of biological specimens, including cell’s internal structures called organelle and is important in magnifying the focused area. Plants are classified into four main groups, namely, ferns, mosses, flowering and confers. This paper finds that ...

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 ...
