What type of stems do gymnosperms have?
Gymnosperms have woody stems, which are typically covered in a thick layer of protective bark. The stems of gymnosperms also often contain vascular tissues for water and nutrient transport.
Gymnosperms have transport tubes so they are called what plants?
Gymnosperms are called vascular plants because they possess transport tubes, specifically xylem and phloem, which facilitate the movement of water, nutrients, and food throughout the plant. This vascular system is essential for their growth and survival, allowing them to thrive in various environments. Unlike non-vascular plants, gymnosperms can efficiently transport resources over longer distances.
How is passive transport from active transport?
The movement of materials across the cell membrane without using cellular energy is called passive transport. The movement of materials against a concentration difference is known as active transport. Active transport requires energy.
Why is a pine tree considered to be more similar to the hibiscus plant than to a fern?
Gymnosperms, such as pine trees, and angiosperms, such as hibiscus, both sport an important evolutionary feature that ferns do not. Gymnosperms and angiosperms both make seeds through sexual reproduction, while ferns produce spores through a type of asexual reproduction. (the latin word sperma means seed.)
What cell transport materials?
the lysomes if not what else
How did Evolution in fruit habit of gymnosperm?
Evolution in fruit habit of gymnosperms occurred through the development of structures such as cones and seeds to protect and aid in the dispersal of their reproductive materials. Over time, natural selection favored those gymnosperms with more effective fruit structures, leading to the diverse array of fruit habits seen in gymnosperms today.
A twisted membrane with portions that breakoff to form vesicles that transport materials?
This process is called endocytosis, where the cell membrane invaginates to form vesicles that transport materials into the cell. These vesicles can then fuse with other organelles or transport materials to other parts of the cell.
This venn diagram says complete and contrast the functions of arteris and veins?
Similarities : used in circulatory system, transport materials, differences : arteries are thicker, and used to transport materials to the cells veins are thinner, and used to transport materials from the cells to areas of the excretory system.
Naked seed plants are called?
Gymnosperms
What traits are shared by modern gymnosperms and angiosperms?
Modern gymnosperms and angiosperms both produce seeds, have vascular tissues for water and nutrient transport, and exhibit alternation of generations in their life cycle. Additionally, both groups have evolved flowers for reproduction, although gymnosperms have unenclosed seeds while angiosperms have seeds enclosed within a fruit.
Distinguish between active and passive transport?
Active Transport is the passage of materials across the membrane through the expenditure of energy. Passive Transport is the passage of materials across the membrane without the expenditure of energy. Bulk Transport is the type of active transport. Diffusion and Osmosis are type of passive transport.
What is this method of molecular transport is called?
Molecular Transport (in cells) is the movement of materials across a cell membrane. The two kinds of Molecular Transport used in organisms are Active Transport and Passive Transport. Active Transport- materials move across the plasma membrane with the use of energy (like Adenosine Triphosphate) Passive Transport- materials move accross the plasma membrane without the use of energy
