Guiding Question

How are these plant organs related to photosynthesis and cellular respiration?

Plant Organs – Photosynthesis and Cellular Respiration

•Roots:

•Anchoring the plant to the soil

•Absorbing water and minerals and transporting them upwards

•Storing the products of photosynthesis (Glucose)

•Bulbous roots store starch.

•Aerial roots and prop roots are two forms of above-ground roots that provide additional support to anchor the plant.

•Some tap roots, such as carrots, turnips, and beets, are adapted for sugar/starch storage.

•Epiphytic roots enable a plant to grow on another plant

Multiple Choice

How do the roots of a plant contribute to the process of photosynthesis?

• Roots do not participate in photosynthesis.

• By producing glucose through the breakdown of carbon dioxide

• By absorbing water and minerals necessary for photosynthesis.

• By releasing oxygen into the atmosphere.

Plant Organs – Photosynthesis and Cellular Respiration

•1.  Epidermis – absorption and protection

•2. Cortex – Thick area of storage parenchyma cells (Stores products of photosynthesis)

•5. Vascular Cylinder – Center portion of the root composed of xylem and phloem

•6. Xylem – Carries water up the plant

•7. Phloem – Tubes that transport glucose throughout the plant

•8. Root hairs – Increase surface area for the absorption of water

Plant Organs – Photosynthesis and Cellular Respiration

•Stems

•Support to the plant

•Holding leaves

•Flowers and buds

•Connect the roots to the leaves

•Transporting absorbed water and minerals from the roots to the rest of the plant

•Transporting sugars from the leaves to roots or mitochondria in other places throughout the plant

Multiple Choice

What reactant in photosynthesis do stem and roots bring to the chloroplast?

• Carbon Dioxide

• Glucose

• Oxygen

• Water

Plant Organs – Photosynthesis and Cellular Respiration

•Leaves

•Main site for photosynthesis

Plant Organs – Photosynthesis and Cellular Respiration

Multiple Choice

The function of stomata is

• to carry out photosynthesis.

• to transport dissolved sugars.

• to allow for gas exchange.

• to transport water and dissolved minerals.

Plant Tissues – Photosynthesis and Cellular Respiration

Dermal Tissue - covers and protects the plant to prevent water loss. It also allows for CO2 and O2 gas exchange.

Vascular Tissue – allows for the transport of water and glucose from the roots to the leaves of the plant.

Ground Tissue - main site for photosynthesis in the leaves, also provides support and structure.

Plant Cells – Photosynthesis and Cellular Respiration

Cuticle – Prevent water loss

Stomata – Openings that allow gas exchange for photosynthesis and cellular respiration

Guard Cells – Surround each leaf stoma, controlling its opening and closing. Regulate the uptake of carbon dioxide and the release of oxygen and water vapor

Transpiration

Transpiration is the loss of water from the leaves when the stomata are open.

Multiple Choice

The function of the cuticle is

• to prevent water from evaporating from the leaf.

• to allow for gas exchange at the top of the leaf.

• to transport water and dissolved minerals.

• to transport dissolved sugars.

Multiple Choice

Gas exchange in the leaf to do photosynthesis is done through the what?

• stomata

• chloroplasts

• roots

Multiple Choice

What cells control water loss in a plant?

• Stomata

• Xylem

• Guard

• Epidermis

Plant Structures – Photosynthesis and Cellular Respiration

Parenchyma/ Palisade Cells (Ground Tissue) – Cells that have lots of chloroplasts, where photosynthesis happens in plants

Underneath the Cuticle and Epidermis

Plant Structures – Photosynthesis and Cellular Respiration

Phloem (Vascular Tissue)- moves sugar from the site of photosynthesis to other parts of the plant

Xylem (Vascular Tissue) – moves water + minerals from the roots to different parts of the plant

Xylem only flows from roots to leaves.

Phloem flows two ways, taking water and food back and forth in the plant.

Multiple Choice
