Plant Tissues
This vascular tissue ensures water and minerals travel efficiently throughout the plant.
What is xylem?
Acting as the bridge between the stem and the leaf blade, this structure is crucial for leaf attachment.
What is the petiole?
Found at the tips of roots and shoots, this meristem is key to a plant’s vertical growth.
What is the apical meristem?
In cacti, these leaf modifications help conserve water by reducing surface area.
What are spines?
These hair-like outgrowths on plant surfaces reduce water loss and deter herbivores.
What are trichomes?
Vital for transporting sugars, this tissue supports the plant’s food distribution system.
What is phloem?
Tiny pores on the leaf’s surface, they regulate gas exchange and water loss.
What are stomata?
Increasing the diameter of stems and roots, this type of growth expands a plant’s girth.
What is secondary growth?
These colorful leaf-like structures often take over the role of attracting pollinators in place of petals.
What are floral bracts?
Packed with chloroplasts, these cells are key to a plant’s energy production.
What are chlorenchyma cells?
Covering the plant’s outer layer, this tissue provides protection from environmental elements.
What is the epidermis?
These cells flank the stomata and are responsible for their opening and closing.
What are guard cells?
These specialized meristems located in internodes are responsible for rapid stem elongation.
What are intercalary meristems?
This iconic plant has leaves that snap shut to capture unsuspecting insects.
What is the Venus flytrap?
The primary substance in plant cell walls, it gives plants their rigidity.
What is cellulose?
Known for storage and photosynthesis, this tissue plays a key role in plant metabolism.
What is ground tissue?
This layer of cells, packed with chloroplasts, is where most of the leaf’s photosynthesis occurs.
What is the palisade mesophyll?
These tiny hair-like structures increase a plant’s surface area for water and nutrient absorption.
What are root hairs?
These cone-shaped leaves trap rainwater and drown insects, providing nutrition to carnivorous plants.
What are the leaves of pitcher plants?
This waxy layer on the surface of leaves helps prevent excessive water loss.
What is the cuticle?
With its lignified cell walls, this tissue offers structural support to plants.
What is sclerenchyma?
These types of leaves are divided into smaller segments, each called a leaflet.
What are compound leaves?
This layer of cells creates wood by producing secondary xylem, essential for tree growth.
What is the vascular cambium?
Found in arid regions, these leaves have transparent tips that allow sunlight to penetrate deep into the plant.
What are window leaves?
The process where water vapor exits a plant, primarily through stomata, is called this.
What is transpiration?
