Review Module 14

Module 14 Review Exploring Creation with Biology

QuestionAnswer
Name the three most common leaf mosaics. Whorled Alternate Opposite
What are the ten common leaf shapes? Linear Elliptical Oval Deltoid Cordate Orbicular Lobed Cleft Needlelike Scalelike
What are the five common leaf margins? Entire Serrate Dentate Crenate Undulate
What are the three common leaf venations? Parallel Pinnate Palmate
What is the location and function of palisade mesophyll in a plant? In the leaf: Photosynthesis
What is the location and function of spongy mesophyll in a plant? In the leaf: Photosynthesis
What is the location and function of epidermis in a plant? Leaf, root, and stem: Protection
What is the location and function of xylem in a plant? Leaf, root, and stem: Transports water and minerals
What is the location and function of phloem in a plant? Leaf, root, and stem: Transports food and organic substances
What is the location and function of chollenchyma in a plant? Vein of leaf: Support
What controls the opening and closing of the stomata on a leaf? Guard cells
Why is the bottom of a leaf typically lighter than the top? The spongy mesophyll layer, which has fewer green photosynthetic cells with more space, is usually on the underside of a leaf.
Name two types of pigments that cause leaves to be a color other than green. Carotenoids and Anthocyanins
If a tree has no abscission layer, will it be deciduous? No
Where is the abscission layer? Between the stem and petiole
Name the four regions of a root. Root Cap - Meristematic - Elongation - Maturation
Where are undifferentiated cells in a root? Meristematic region
What allows woody stems to have no limit to their growth, unlike herbaceous stems? The cork cambium in a woody stem produces more bark when the bark cracks due to growth. But herbaceous stems do not have cork cambium and thus would crack, exposing the stem to injury and disease.
What is the function of vascular cambium? Produces new vascular tissue.
What kind of vascular tissue makes up most of the wood in a woody stem? Xylem
What kind of vascular tissue is found in the inner bark of a woody stem? Phloem
What is the dominant generation in the moss life cycle? Gametophyte: Haploid
A fern has antheridia and archegonia. Which part of the fern life cycle is it in? Is it dominant? Gametophyte: Not dominant
Why are plants from phylum Bryophyta relatively small? They have no vascular tissue to transport nutrients throughout the plant.
A fifteen foot tall plant has a root system four feet deep. Is it fibrous or taproot? Fibrous
What are the male and female reproductive organs in a tree from phylum Coniferophyta? Female is the seed cone, male is the pollen cone
What is the fundamental difference between monocots and dicots? The number of cotyledons produced in the seed.
A plant produces seed cones and pollen cones. Is it vascular? To what phylum does it belong? Vascular, phylum Coniferophyta
A plant produces flowers. To what phylum does it belong? Phylum Anthophyta
What is the abscission layer? Structure in deciduous trees between the stem and petiole that causes the leaves to die in autumn.
What are anthocyanins and how do they work? A group of pigments that can give plants a pigment other than green. They work through leaf PH.
Be able to recognize monocot or dicot vascular bundles. Study Figure 14.12
Name two differences between monocots and dicots. Leaf venation: parallel monocots, netted dicots; Fibrovascular bundles: location and appearance differ; Number of petals: 3 or 6 monocots, 4 or 5 dicots
