Question

Describe the leaf shape and quality compared to other specimens. Compare and contrast the male and female cones. Record your observations here. What advantage is directly related to a plant being an "evergreen"? State at least 2 key adaptations that allowed gymnosperms, especially conifers. enhanced survival in dry/arid conditions. Observe a scale from a female cone, if available. Sketch and label what you see. What is a "pine nut"? A conifer seed will be found on which type of cone? Why? Angiosperms Watch video. Observe specimens and models. Identify floral structures- 1. How does the Bee-wing orchid "trick" bees? On a separate piece of paper: Draw a live flower. Label: sepals, petals, stamens, filament, anther, ovary, style, stigma, carpel. In your sketch, indicate where you can find pollen where an ovule (which includes the egg) may develop and where a seed may develop.

Help me answer question 5,6,7,8,9 relating to gymnosperm. Thanks

Answer 1

5. The advantages of being evergreen include;

Less nutrient loss.

Leaves are persistent

6. Conifers ate considered As xerophytes because;

The leaves are needle shaped to reduce surface area of evaporation.

The presence of thick cuticle and Sunken stomata prevent water loss through epidermis.

7.

8. Pine nuts are the edible seeds of Pinus. These are highly nutritious for humans.

9. The seeds are formed within the megasporophylls which are spirally arranged around the axis of the cone, these are formed in the female cone because of more protection.
