Some plants produce roots that invade the tissues of a host plant. Parasites such as mistletoe, which are capable of photosynthesis, obtain only water and minerals from their host. Others, like the indian pipe and pine drops, produce no chlorophyll and depend entirely on food drawn from their host.
Alternation of generations is a type of life cycle found in terrestrial plants and some algae in which subsequent generations of individuals alternate between haploid and diploid organisms. This can be contrasted to sexual reproduction in animals, in which both haploid and diploid cells are found in every generation.
Type of plant tissue specialized to transport needed substances throughout the plant, such as food and water roots function for absorption of water and minerals, anchorage, food storage (some), reproduction (some).
If we consider plants, based on their height, some are too short while some are too tall to climb. For example – short plants have greenish, soft, and tender stems, while big and tall plants or trees have a thick, strong and woody stem which are hard to break.
We discuss what plants need to grow, how to water plants, and more.
The spermatophytes, which means seed plants, are some of the most important organisms on earth. Life on land as we know it is shaped largely by the activities of seed plants. Soils, forests, and food are three of the most apparent products of this group.
• some substances like carbon dioxide or oxygen can move across the cell membrane by a process called diffusion. Osmosis • the movement of water molecules through selectively permeable membrane along the concentration gradient is called osmosis.
Some fruits are developed without fertilization and are known as parthenocarpic fruits and the process is known as parthenocarpy. Thus, we see how different parts of a plant help in the growth and development of a plant. All the plant parts are beneficial and work in coordination with each other.
For example, some animals like plasmodium and roundworms, a few plants like cuscuta (amarbel) and several fungi and bacteria. (iii) holozoic nutrition: the holozoic nutrition is that nutrition in which an organism takes the complex organic food materials into its body by the process of ingestion; the ingested food is digested and then absorbed.
Plants are surrounded by diverse types of mesofauna and microbial organisms, some of which can contribute to biological control of plant diseases. Microbes that contribute most to disease control are most likely those that could be classified competitive saprophytes, facultative plant symbionts and facultative hyperparasites.
(b) shrubs: some plants have branches arising from the base of the stem. (c) trees: some plants are very tall and have hard and thick stem. Creepers and climbers: the stem of some plants are very thin and weak.
Living parenchyma cells found in all plant organs perform the basic metabolic functions of cells: respiration, photosynthesis, storage, and secretion. Parenchyma cells usually live for one to two years but have been known to live hundreds of years in some plants, such as cactus.
Some prefer a cool walk in the woods, others love going to a hot beach. Plants have their preferences too, and it is up to you to find out about your new friend and make things right.

Since reproduction is through the vegetative parts of the plant, it is known as vegetative propagation. Bryophyllum (sprout leaf plant) has buds in the margins of leaves. If a leaf of this plant falls on a moist soil, each bud can give rise to a new plant. Bryophyllum (sprout leaf plant) the roots of some plants can also give rise to new plants.

Inside the multicellular sporangia, the diploid sporocytes, or mother cells, produce haploid spores by meiosis, where the 2n chromosome number is reduced to 1n (note that many plant sporophytes are polyploid: for example, durum wheat is tetraploid, bread wheat is hexaploid, and some ferns are 1000-ploid).
These are stored in plant tissues and are an essential part of the diet of animals that eat plants.
