Lesson Objectives 12 March 2021 Plant tissues and organs systems Entry: in silence: Explain how plants are adapted for photosynthe sis. 1. Format your desk. 2. Write and underline the date and title. 3. Write the LO: objective. DNA: 1. Draw using a pencil a diagram of a plant, include above and below the soil. 2. Label the main organs on the diagram. 3. Give the function of each organ. Growing Together - Reaching Higher

Lesson Objectives Self-assess Leaves - absorb sunlight for photosynthesis. Explain how plants are adapted for photosynthe sis. Stem - transport water and nutrients and to support the leaves and flowers. Flower – contains the reproductive organs of the plant. Roots - anchor the plant in the ground and to absorb water from the soil. Growing Together - Reaching Higher

Lesson Objectives By the time you leave my room, you will be able to: • 1. Describe how plant organs are involved in the transport system. • 2. Explain how the structures of tissues in the leaf are related to their functions Explain how plants are adapted for photosynthe sis. Growing Together - Reaching Higher

Lesson Objectives Plant tissues The main plant tissues are: • • Explain how • plants are • adapted for photosynthe • epidermal palisade mesophyll spongy mesophyll xylem and phloem meristem sis. Growing Together - Reaching Higher

Lesson Objectives Inside a leaf Explain how plants are adapted for photosynthe sis. Growing Together - Reaching Higher

Lesson Objectives Structure of a leaf Waxy Cuticle Upper epidermis Chloroplast Palisade layer Explain how plants are adapted for photosynthe sis. Spongy Layer Stomata Guard Cell Air Space Lower epidermis Growing Together - Reaching Higher

How leaves are adapted for photosynthesis? Waxy cuticle Palisade Cells Spongy mesophyll Guard cell and stomata

Lesson Objectives Checking for Understanding Please label your diagram of a leaf. Explain how plants are adapted for photosynthe sis. Growing Together - Reaching Higher

Lesson Objectives Waxy cuticle Explain how plants are adapted for photosynthe sis. Growing Together - Reaching Higher

Lesson Objectives Palisade cells Explain how plants are adapted for photosynthe sis. Growing Together - Reaching Higher

Lesson Objectives Spongy mesophyll Explain how plants are adapted for photosynthe sis. Growing Together - Reaching Higher

Lesson Objectives Guard cells and stomata Explain how plants are adapted for photosynthe sis. Growing Together - Reaching Higher

Lesson Objectives Checking for Understanding Leaf structure How related to function Epidermis & Tightly packed cells to cover the surface and waxy cuticle protect underlying cells. Cells secrete a waxy substance to reduce water loss by evaporation. Explain how plants are adapted for photosynthe sis. Palisade mesophyll Packed with chloroplasts to absorb sunlight for photosynthesis. Spongy mesophyll Rounded cells with lots of air spaces between them. Has a large surface area for gas exchange, oxygen for carbon dioxide. Lower epidermis Has lots of tiny pores called stomata which allow gases to diffuse into and out of the leaf. The opening and closing of the stomata are controlled by guard cells. Close to reduce water loss. Growing Together - Reaching Higher

Lesson Objectives Do Not Disturb Describe how plants are adapted for photosynthesis. Explain how plants are adapted for photosynthe sis. Include the following: • A description of how the parts of a leaf are adapted • Why are palisade cells tall and thin (vertical), rather than horizontal? • Why do root hair cells not have chloroplasts? • Why is the waxy cuticle found on the top of the leaf and not at the bottom? (Think about what increases evaporation? ) • Why do plants that live in water not need a waxy cuticle? • How do you think the waxy cuticle for a plant found in the desert would differ to that found in the UK?

Lesson Objectives Exit Ticket Describe three ways that a leaf is adapted for photosynthesis. Explain how plants are adapted for photosynthe sis. Growing Together - Reaching Higher

Exit Routine – make it sharp and purposeful
