- Their cells and structures are specialized to take in light and allow for gas exchange with the air around them. They also contain vascular structures that transport water from the roots into the cells that carry out photosynthesis.

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.
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. Part of Combined...
Nucleus: Contains genetic material, including DNA, which controls the cell’s activities. Cell membrane : Its structure is permeable to some substances but not to others.
Describe the microscope internal structure of leaves, including the epidermis, mesophyll, and vascular bundles. Compare the adaptations of mesophytic, hydrophytic, and xerophytic leaves. Identify the unique features of pine and corn leaves. Compare the structures of sun and shade leaves.
The cells have sieve plates at the ends (marked by arrows). In the event of an injury, P-protein rushes to form a slime plug (B) and close the wound. Sieve tubes are alive but contain very little cell contents, they do not even have a nucleus.
Dicot leaf. Leaves, and the structures they contain, play key roles in photosynthesis. When it comes to photosynthesis, the most important parts of the plant are the leaves. Their cells and structures are specialized to take in light and allow for gas exchange with the air around them.
