When it comes to drawing software for biological sciences, particularly for plant anatomy, there are several options available, each with its own set of features and benefits. Here are some popular choices:

1. Adobe Illustrator: Adobe Illustrator is a powerful vector graphics editor that is widely used in scientific illustration, including plant anatomy. It offers precise control over shapes, colors, and lines, making it suitable for detailed scientific diagrams. It also integrates well with other Adobe Creative Cloud applications.

2. CorelDRAW: CorelDRAW is another vector graphics editor that is popular among scientific illustrators. It offers similar features to Adobe Illustrator and is known for its ease of use and broad range of tools. CorelDRAW is often used for creating complex illustrations, including those related to plant anatomy.

3. Inkscape: Inkscape is a free and open-source vector graphics editor that is widely used in the scientific community. It offers many of the same features as Adobe Illustrator and CorelDRAW, including support for complex shapes, paths, and text. Inkscape is a great option for those who prefer open-source software or have budget constraints.

4. BioRender: BioRender is a web-based platform specifically designed for creating scientific illustrations, including those related to biology and plant anatomy. It offers a library of customizable templates and icons tailored to the life sciences. BioRender simplifies the process of creating professional-quality scientific diagrams and is popular among researchers and educators.

5. Sketch: Sketch is a vector graphics editor that is popular among designers and illustrators. While not specifically tailored to biological sciences, it offers a range of features that can be useful for creating scientific illustrations, including plant anatomy diagrams. Sketch is known for its intuitive interface and robust set of design tools.

Ultimately, the best drawing software for plant anatomy in biological sciences depends on your specific needs, preferences, and budget. It may be helpful to explore the features of each option and perhaps try out a few different programs to see which one best suits your workflow.

For iPad users we can add Procreate, which is a very versatile tool creating very nice compositions. Also, you can use ArtRAGE

Rouhangiz Abbas Azimi , traditionally we use what our colleagues and professional communities use. All the answers above are good packages. Do you have full access to internet and software ??? And do need to analyze and draw ?? - lastly, if you're a new user to "vector" style drawing user expect a learning curve.

All of the answers given so far are great. The one thing I would underscore is the learning curve. A skilled user can make great art out of any of the packages. But what skill level does the user have, how long does it take them to learn new software, and when does it have to be done? Lastly, although most packages export to many different file formats now, I would be sure whatever you use is compatible with how the final illustrations must be output. Do they need to export to other programs? Will the finals be used for screen? Print? 2D? 3D? Animated? Do they need to be high resolution? How high? Follow your needs all the way through and then decide on the package.

Adobe Illustrator is widely regarded as one of the best drawing software for illustrating plant anatomy in the field of plant sciences. Its precision, versatility, and robust toolset make it a go-to choice for creating detailed and professional botanical diagrams.
