PHOTOSYNTHESISAEROBIC RESPIRATION H 2 O and CO 2 are raw materials C 6 H 12 O 6 and O2 are raw materials C 6 H 12 O 6 and O 2 are products H 2 O and CO 2 are products Takes place in chloroplasts Takes place in mitochondria

3 main parts of a plant Roots Stems Leaves

Roots

Anchor plants Absorb water and minerals from soil Store food

Stems

Support Hold the leaves up Contain vascular tissue:

–Xylem: carries H 2 O UP the plant –Phloem: carries FOOD from leaves throughout the plant

2 types of stems: Herbaceous stemsWoody stems

Leaves Site of PHOTOSYNTHESIS

Guard cells Stomate AB C D E Palisade layer Vein Spongy latyer

Let’s summarize… 1. Identify the three main parts of plants. 2. Describe the importance of roots. 3. Describe what is found inside of stems. 4. Identify the function of xylem and phloem. 5.Where does photosynthesis occur in plants? 6. Why are leaves flat and broad? Roots, stems and leaves Absorb water, anchor plants into soil Vascular tissue (xylem and phloem) Leaves To absorb more sunlight Xylem transports water UP. Phloem transports food throughout the plant.

Identify the plant structure described. a.Support the plant’s branches and leaves. b.Absorbs water and dissolved substances. c.Site of photosynthesis. d.Anchors plants to keep them in their location. e. Transports water and substances to the leaves f. Can also store food for plants to use. g. Identify the structures that enable roots to absorb more water. h. Contains vascular tissue known as xylem and phloem. Stems Roots Leaves Roots Stems Roots Root hairs Stems

In which part of the plant does most food-making occur? 1. root 2. root hair 3. leaf 4. stem

The tissue that carries water and minerals up from the roots through a plant is the 1.cambium 2.xylem 3.phloem 4.tuber

Water is absorbed into the plant through the 1.root hairs 2.leaves 3.chloroplasts 4.stem

The tissue the carries food substances down from the plant’s leaves is the 1.cambium 2.xylem 3.phloem 4.tuber

Which concept would be correctly placed in box X? (1) use and disuse (2) variation (3) transmission of acquired traits (4) changes in nucleic acids

1.What part of Darwin’s Theory of Natural Selection is this diagram representing? 2.Which has the favorable adaptation? How do you know? variation Medium  they are able to survive better.

Describe the conclusion that can be made about the fossils in layer A and layer B. Fossils in layer A are older and less complex than the fossils in layer B.

The diagram above shows a series of bone structures in four different species of vertebrates. 1.What are these structures called? 2. Explain how these structures support the theory of organic evolution. Homologous structures Because they are similar in structure, these organisms may have evolved from a common ancestor.

“Evolution is the result of long periods of stability interrupted by geologically brief periods of significant change.” This concept is called: 1.gradualism 2.natural selection 3.geographic isolation 4.punctuated equilibrium

The Florida panther, a member of the cat family, has a population of fewer than 100 individuals and has limited genetic variation. What inference can be made according to the information given? If there is a major environmental change and their adaptations are no longer favorable, the species will become extinct.

1. Which letter represents a common ancestor for species C and E? 2. Which species are least likely to be vital parts of a present-day ecosystem? K E and J

The substance is green plants that captures the sun’s light energy is 1.chlorophyll 2.mesophyll 3.phloem 4.cuticle

During photosynthesis, molecules of carbon dioxide and water are changed into 1.oxygen and carbon dioxide 2.glucose and water 3.glucose and chlorophyll 4.oxygen and glucose

Which of the following materials is not needed for photosynthesis? 1.sunlight 2.chlorophyll 3.water 4.oxygen

A process in which glucose is broken down to release energy is called 1.diffusion 2.respiration 3.photosynthesis 4.osmosis

Aerobic respiration requires 1.oxygen 2.carbon dioxide 3.light 4.chlorophyll

One substance that is generated from aerobic respiration is 1.ATP 2.protein 3.glucose 4.oxygen

Respiration occurs in 1.chloroplasts 2.nuclei 3.mitochondria 4.ribosomes
