- Leaves enable photosynthesis to occur. Photosynthesis is the process by which leaves absorb light and carbon dioxide to produce glucose (food) for plants to grow. Leaves are adapted to perform their function, eg they have a large surface area to absorb sunlight.

How are leaves adapted?
Plant leaves are adapted for photosynthesis and gas exchange. Roots absorb water and mineral ions through root hair cells and are transported up the plant by the xylem.

Leaves are complex organs made of several layers of tissue. These are the epidermis, the palisade mesophyll layer, the spongy mesophyll layer, and vascular bundles. 1. Theepidermis is the “skin” of a leaf. Sometimes there is also a cuticle outside the epidermis. This is a waxy layer that helps prevent water loss. This is especially important in dry...
Chloroplasts are specialized organellesthat are only found in plant cells. Chloroplasts contain thylakoids. Thylakoids are the specific structures responsible for photosynthesis. Some thylakoids float freely in the fluid that fills the chloroplast. This fluid is called stroma. But most thylakoids are in stacks called grana. A single grana is called...
The stomata in a leaf’s surface are surrounded by specialized cells called guard cells. Guard cells regulate the opening and closing of stomata. They open by taking in water. This causes them to swell and take on a crescent shape. They close by releasing water. This causes them to shrink and take on a long, thin shape. Stomata allow oxygen (O2) and...
Each guard cell contains a large vacuole, a nucleus and chloroplasts. Generally, when the plant senses good conditions, like bright light or high humidity, its stomata open. This happens when guard cells swell with water through the process of osmosis. The reverse happens when stomata close in poor conditions.
Xylem cells run inside stems of plants from their roots to their leaves. Xylem cells die and their ends break down. This allows them to form long tubes to carry water upwards for photosynthesis.

Jul 12, 2023 · Leaves are the primary food factories in a typical plant. Powered by the sun’s energy, leaves take in water and carbon dioxide and produce oxygen and glucose through photosynthesis. Leaves have specialized cells on their surfaces called guard cells which surround openings called stomata (singular = stoma). Stomata are tiny openings in the ...
Apr 27, 2010 · In most plants, the two surfaces of the leaf are specialized, with the photosynthesizing light harvesting cells concentrated at the upper side and gas-exchanging cells at the lower side. This leaf polarity is also evident in the differential distribution of trichomes and stomata and in the position of cell types in the vascular bundles ( Figure ...
