Study Notes
- The cortex in the center of a dicot stem or monocot root consists of ground tissue.
- Farmers wanting crops with access to groundwater several meters below ground should use a taproot system.
- The layers of cells protecting the root apical meristem are the root cap.
- Pulling out bushes without clearing enough soil around the root system, causes the lateral roots and root hairs to be torn off.
- Epidermis tissue produces root hairs within the zone of maturation.
- Wood in large woody plants is xylem, and bark is phloem and cork.
- Periderm replaces the epidermis in older woody plants.
- The terminal bud would decrease the potential for an increase in plant height if nibbled off.
- Approximately five feet up is where a fifteen-foot tree growing in a fence row will grow since a tree grows longer at the tips of its stem, branches, and roots.
- An axillary bud may produce a lateral branch or a flower.
- Seven bud scale scars on a plant indicate it is seven years old.
- Secondary phloem accumulates to form the wood is not a true statement about woody stems.
- Vascular bundles arranged in a ring which store water and the products of photosynthesis best describe a herbaceous eudicot stem.
- Stolon, rhizomes, tubers, and corms are all stem adaptations instead of root adaptations.
- Phloem cells are hollow and nonliving, and form a continuous pipeline that transports sugars is not true about vascular tissue in plants.
- The photosynthetic mesophyll is made up of an upper spongy layer and a lower palisade layer in eudicots is not a correct statement about leaves.
- The correct order of layers of a leaf from upper to lower surface is cuticle - epidermis - palisade mesophyll - spongy mesophyll - epidermis - cuticle.
- A spongy mesophyll destroyed by an insect would decrease the ability of gas exchange within a leaf.
- Most of the photosynthesis occurs in the mesophyll layer of leaves.
- A submerged-water plant would have no stoma because leaf stoma have the conflicting functions of allowing gaseous carbon dioxide into the leaf, yet preserving the plant's supply of water.
- If you need to identify a plant, but it is winter; cutting the stem and observing scattered vascular bundles indicates it is a monocot.
- It is best to look near the root tip of a plant for a microscope slide of mitosis.
- All of the choices anchor the plant, store the products of photosynthesis, and produce hormones that stimulate stem growth are plant root functions.
- The plant will contain one cotyledon, have parallel veins in the leaves, and the flowers will be in multiples of threes are necessary to classify a plant as a monocot.
- A plant that survives multiple growing seasons due to flower-inducing genes being blocked is described as perennial.
- Protoderm, ground meristem, and procambrium are meristems that arise from the apical meristem, EXCEPT epidermis.
- The epidermis of a plant is not impervious to gas exchange.
- Ground tissue makes up the majority of the interior of the plant.
- The epidermis is the outer protective covering of a plant.
- Vascular tissue transports water and nutrients within a plant.
- collenchyma is not a specialized epidermal cell.
- Parenchyma most closely corresponds to the "typical" unspecialized plant cell.
- Xylem and pholem tissue types are not found only in the zone of cell division of the root tip.
- The endodermis forms a boundary between the cortex and inner vascular cylinder of the root and contains impermeable lignin and suberin.
- Rhizome is an underground horizontal stem.
- The apical meristem arises from the meristems, except for the epidermis.
- Protoderm-vascular tissue is a mismatched meristem and tissue type.
- Collenchyma is composed of cells with primary walls thickened at the corners that provide support for immature parts of the cell body.
- Xylem is composed of hollow nonliving tracheids and vessel elements that transport water and nutrient minerals from the roots to the leaves.
- Phloem contains sieve-tube members and companion cells, and transports organic nutrients made in the leaves.
- Sieve-tube members are vascular tissue cells that are alive but lack a nucleus.
- Phloem transports organic nutrients and sugars from the leaves to the roots.
- Epidermal tissue - parenchyma cells is the incorrect pairing of tissue type with cell type.
- You'd want to tap into pholem tissue layer to extract syrup in a maple tree.
- Damage to the parenchyma cells can lead to a decrease in the plant's ability to run photosynthesis or store the sugars produced from photosynthesis.
- While cell walls, plasmodesmata, and plastids are present, Centrioles are not present during mitosis in plant cells.
