Is cactus a vascular or nonvascular?

Answer. Cactus is an example of a vascular plant. They have xylem and phloem that transports food, water, and minerals from roots to leaves. These plants can propagate to be extremely enormous because nutrients and water are moved on all plant parts.

What type of tissue does a cactus have?

Cacti and other plants have three types of tissue: Ground which forms most of the body of the cactus and functions include photosynthesis, food storage and internal support. Protective or dermal tissue is found in the outer layer of roots, stems and thorns and protects the plant from water loss and other hazards.

Which plant has vascular tissue?

The ferns, gymnosperms, and flowering plants are all vascular plants. Because they possess vascular tissues, these plants have true stems, leaves, and roots.

Do all plants have vascular tissue?

Vascular tissue consists of complex tissues xylem and phloem. ... All plants do not have vascular tissues. Lower plants like Algae, Fungi and Bryophytes lack vascular tissue. These plants are termed Non-vascular plants or atrachaeophytes.

Is a cactus a flowering vascular plant?

More on Vascular Plants

Some examples of vascular plants are duckweed,cacti,giant redwood trees,ferns,conifers,flowering plants, etc.

Is cactus flowering or non flowering?

Cacti are all flowering plants, but some have more prominent blooms and there are a few, such as Mammillaria, Gymnocalycium and Parodia, that will flower quite easily with impressive, colourful displays.

Is Fern a vascular plant?

fern, (class Polypodiopsida), class of nonflowering vascular plants that possess true roots, stems, and complex leaves and that reproduce by spores. ... The ferns constitute an ancient division of vascular plants, some of them as old as the Carboniferous Period (beginning about 358.9 million years ago) and perhaps older.

Are gymnosperms vascular?

As vascular plants, gymnosperms contain two conducting tissues, the xylem and phloem.

Is xylem a vascular tissue?

xylem, plant vascular tissue that conveys water and dissolved minerals from the roots to the rest of the plant and also provides physical support. Xylem tissue consists of a variety of specialized, water-conducting cells known as tracheary elements.

Which plant has no vascular tissue?

Non-vascular plants, or bryophytes, are plants that lack a vascular tissue system. They have no flowers, leaves, roots, or stems and cycle between sexual and asexual reproductive phases. The primary divisions of bryophytes include Bryophyta (mosses), Hapatophyta (liverworts), and Anthocerotophyta (hornworts).

Which of the following have swimming sperm?

The "lower" land plants are famous for their swimming sperms. These vascu- lar and nonvascular cryptogams (plants without seeds) include the ferns, horse- tails, lycopods, liverworts, hornworts, and mosses.

Do cactus have spines?

Those prickly spines that are so characteristic of the cactus family are actually modified leaves! Cactuses don't have the kind of leaves like a maple or oak tree. ... Over time, those leaves evolved into the spiky spines we see on cactuses today because they help the plants survive in hot, dry environments.

What are spines on a cactus?

Spines are also modified leaves. In cacti, spines are wholly transformed leaves that protect the plant from herbivores, radiate heat from the stem during the day, and collect and drip condensed water vapour during the cooler night.

Why do cacti have spines?

So, one reason for why cacti have needles is to prevent thirsty or hungry animals from eating or damaging the plant. ... These spine clusters almost act like mini-umbrellas that help to shade the plant. By shading the cactus, these spines also help prevent the cactus from losing water through evaporation.
